'''Per Mertesacker''' ({{IPA|de|ˈpeːɐ̯ ˈmɛɐ̯təsʔakɐ}}; born 29 September 1984) is a German [[Association football|football]] [[Coach (sport)|coach]] and former professional [[Football player|player]] who played as a [[centre back]]. He is the current manager of the [[Arsenal F.C. Under-23s and Academy|Arsenal Academy]].<ref>{{cite web |url=https://www.arsenal.com/news/mertesacker-lead-arsenal-academy|title=Per Mertesacker to lead Arsenal academy|date=23 July 2025 }}</ref>

Mertesacker began his senior career after being promoted from the youth ranks at [[Bundesliga]] club [[Hannover 96]], making his senior league debut in November 2003. He was soon dubbed "the Defence Pole" ("''die Abwehrlatte''") by German tabloids, and gained a reputation for his exceptional disciplinary record, going 31 league games without being booked.<ref>{{cite web |url=http://www.arsenal.com/news/news-archive/find-out-more-about...-per-mertesacker |title=Find out more about...

His tenure at the club was characterized for his ability to read play and stifle the build-up play to opposition attacks, establishing himself as a defender with a quiet-but-effective game, and a core-component of the Bremen team that won the [[2009 DFB-Pokal Final|2009 DFB-Pokal]], and finished as runner-up in the [[2009 UEFA Cup Final|2009 UEFA Cup]].

After being singled out for praise for his performances at the [[2010 FIFA World Cup]], and with his contract at Bremen dwindling, he transferred to [[Premier League]] club [[Arsenal F.C.|Arsenal]] a year later, for a fee of £8 million.<ref>{{Cite web|url=https://www.arsenal.com/arsenal/players/mertesacker|title=Per Mertesacker|website=www.arsenal.com|language=en|access-date=30 October 2017}}</ref> At Arsenal, Mertesacker quickly established himself as the first-choice centre back for the club, becoming a mainstay despite sharing several defensive partners over his first two seasons.<ref>{{cite web|url=http://soccernet.espn.go.com/player/_/id/34041/per-mertesacker?cc=3436 |archive-url=https://archive.today/20120721072015/http://soccernet.espn.go.com/player/_/id/34041/per-mertesacker?cc=3436 |url-status=dead |archive-date=21 July 2012 |title = Per Mertesacker | website = ESPN Soccernet | access-date =28 October 2011}}</ref> He eventually built up a solid relationship with fellow defender [[Laurent Koscielny]], and the duo would star as Arsenal ended their nine-year trophy drought by winning the [[2014 FA Cup Final|2014 FA Cup]]. He would later captain and score for the side in their retention of the trophy [[2015 FA Cup Final|a year later]], before becoming the club's outright [[Captain (association football)|captain]] in 2016. He would again star in his third victory of the trophy in [[2017 FA Cup Final|2017]]. However, injuries derailed the latter stages of his career at Arsenal, and was used sparingly during his final two seasons, being forced to retire in 2018.

At national level, Mertesacker played for Germany at the [[Germany national under-20 football team|under-20]] and [[Germany national under-21 football team|under-21]] levels, prior to debuting for the senior side in 2004 against [[Iran national football team|Iran]]. Upon his debut, Mertesacker established himself as Germany's first-choice centre back for ten years, participating in [[European Football Championship|UEFA European Championship]] in [[UEFA Euro 2008|2008]] and [[UEFA EURO 2012|2012]], as well as the [[2006 FIFA World Cup|2006]], [[2010 FIFA World Cup|2010]] and [[2014 FIFA World Cup]]s, winning the latter. He would retire from international competition following this win.<ref>{{cite web | url = https://www.kicker.de/auch-mertesacker-hoert-als-nationalspieler-auf-609895/artikel | title = Auch Mertesacker hört als Nationalspieler auf | language = de | website = [[Kicker (magazine)|Kicker]] | date = 15 August 2014 | access-date = 15 August 2014}}</ref>

During his time at Hannover 96, he became good friends with the late [[Robert Enke]], and along with [[Michael Ballack]], presented the laurel during Enke's memorial service. He later started a temporary account through his foundation (''Per Mertesacker Stiftung'') to collect donations for Enke's widow.<ref>{{cite web | url = http://pms.mertesackerandfriends.de/startseite.html | title = Per Mertesacker Stiftung | publisher = Per Mertesacker Stiftung | language = de | access-date = 17 September 2010 | archive-url = https://web.archive.org/web/20100220105421/http://pms.mertesackerandfriends.de/startseite.html | archive-date = 20 February 2010 | url-status = dead | df = dmy-all }}</ref>

===Werder Bremen===
[[File:Per mertesacker bayern.jpg|thumb|upright|left|Mertesacker playing for [[SV Werder Bremen|Werder Bremen]]]]
In August 2006, Mertesacker moved to [[SV Werder Bremen|Werder Bremen]] in a €5 million transfer deal after a highly impressive performance in the [[2006 FIFA World Cup|2006 World Cup]], in which Germany finished third.<ref>{{cite news|title=Summer spree for the Bundesliga|url=https://www.fifa.com/worldfootball/clubfootball/news/newsid=104855.html|archive-url=https://web.archive.org/web/20121112170752/http://www.fifa.com/worldfootball/clubfootball/news/newsid=104855.html|url-status=dead|archive-date=12 November 2012|publisher=[[FIFA|fifa.com]]|date=9 August 2006 | access-date =17 September 2010}}</ref> At the time of his transfer, he and Brazilian midfielder [[Diego (footballer, born 1985)|Diego]], who joined from [[FC Porto|Porto]], were jointly Bremen's most expensive signings in the club's history.<ref>{{cite web |title=Mertesacker verstärkt Bremen|url=http://www.spiegel.de/sport/fussball/norddeutscher-tauschhandel-mertesacker-verstaerkt-bremen-a-430634.html|work=[[Der Spiegel]]|date=8 August 2006|language=de | access-date = 18 December 2018}}</ref> Despite missing the first month and a half through an injury sustained at the World Cup, he quickly made the centre-back position his own upon his return to the starting eleven. In November, he scored his debut Champions League goal in a 1–0 win over [[Chelsea F.C.|Chelsea]] to end the [[Premier League]] winners' unbeaten streak in the season's competition. Upon his first return to the [[AWD-Arena]] for the first game of the second half of the season, he refused to celebrate after scoring against his boyhood club.<ref>{{cite web|title=Das langersehnte Heimspiel|url=http://www.hannover96.de/CDA/aktuelles/96-live/pressespiegel/detailansicht.html?tx_ttnews%5Btt_news%5D=1016&cHash=579daae534|archive-url=https://web.archive.org/web/20071121004728/http://www.hannover96.de/CDA/aktuelles/96-live/pressespiegel/detailansicht.html?tx_ttnews%5Btt_news%5D=1016&cHash=579daae534|publisher=[[Hannover 96]]|archive-date=21 November 2007|date=15 November 2007|language=de | access-date =17 September 2010}}</ref>

The [[2007–08 Bundesliga|2007–08 season]] was a mixed bag for Mertesacker. He started in nearly all of Bremen's league and European fixtures and received his first red card in his professional career in a 6–3 loss against [[VfB Stuttgart]].<ref>{{cite news|title=Mertesacker hit with three-game ban|url=https://www.fifa.com/worldfootball/clubfootball/news/newsid=894608.html#mertesacker+with+three+game|archive-url=https://web.archive.org/web/20081003143002/http://www.fifa.com/worldfootball/clubfootball/news/newsid=894608.html#mertesacker+with+three+game|url-status=dead|archive-date=3 October 2008|publisher=[[FIFA|fifa.com]]|date=1 October 2008 | access-date =17 September 2010}}</ref> Bremen finished runners-up in the league winning only two games fewer than champions [[FC Bayern Munich|Bayern Munich]] and managed to seal a place in the next season's [[UEFA Champions League|Champions League]].

After returning from the [[UEFA Euro 2008|Euro 2008]], Mertesacker again missed the beginning of the new season with a knee injury and through illness. In September, he returned to the starting line-up. He scored the opening goal in the [[DFB-Pokal]] semi-final away at northern rivals [[Hamburger SV]] to break the deadlock after a goalless first half, but the home side equalised, forcing the match into extra time and Bremen eventually triumphed 4–2 on penalties. He was ever present for the rest of the season until injury forced him off in the [[2008–09 UEFA Cup#Semi-finals|UEFA Cup semifinal]] second leg against Bundesliga rivals Hamburg.<ref>{{cite news|title=Werders Nationalspielern drohen bis zu 68 Spiele|url=http://www.weser-kurier.de/Artikel/Werder/5015/Werders+Nationalspielern+drohen+bis+zu+68+Spiele.html|publisher=Weser Kurier|date=16 July 2009|language=de | access-date =17 September 2010}}</ref> It was later revealed that he had torn ligaments in his right ankle and required surgery. He was ruled out for the rest of the season, as well as the [[2009 UEFA Cup Final|UEFA Cup final]] loss against [[FC Shakhtar Donetsk|Shakhtar Donetsk]] and [[2009 DFB-Pokal Final|DFB-Pokal final]], which they won. He scored four goals in all competitions, including a crucial equalizer against [[VfL Wolfsburg]].

Mertesacker began the [[2009–10 Bundesliga|2009–10 season]] well with a 5–0 win over [[FC Union Berlin]] in the [[2009–10 DFB-Pokal]], the first game of the season. In October, he scored his first goal of the season in a 2–0 win against [[TSG 1899 Hoffenheim|1899 Hoffenheim]] and a last-minute equalizer in the clash against table-toppers Bayer Leverkusen in February. He played 33 Bundesliga matches in total, scoring five goals in the process.<ref name="whoscored.com_3181">{{cite web| title=Werder Bremen Squad Archive Summary Bundesliga 2009/10|url=http://www.whoscored.com/Teams/42/Archive?stageId=3181|publisher=WhoScored.com | access-date =15 September 2011}}</ref>

In the [[2010–11 Bundesliga|2010–11 season]], Mertesacker made 30 Bundesliga appearances, scoring two goals. He averaged 46.3 passes per game, the third-highest in the Bremen squad, and the second highest pass success rate, with 82%, demonstrating another facet of his game.<ref>{{cite web|title=Werder Bremen Squad Archive Summary Bundesliga 2010/11| url=http://www.whoscored.com/Teams/42/Archive?stageId=4448|publisher=WhoScored.com | access-date =15 September 2011}}</ref>

Over the course of his final two seasons at Bremen, Mertesacker received just one yellow card in 63 league matches. He averaged less than one foul per game, cementing his reputation as an astute reader of the game, defying critics' predictions that his height would render him clumsy and having a tendency to frequently concede fouls.<ref name="whoscored.com_3181" />

===Arsenal===

[[File:Per Mertesacker.jpg|thumb|right|Mertesacker and Arsenal against [[Borussia Dortmund]] in the [[UEFA Champions League]]]]
On 31 August 2011, [[Arsenal F.C.|Arsenal]] confirmed they had signed Mertesacker on a four-year contract. He was presented the number 4 shirt previously worn by former team captain [[Cesc Fàbregas]]. In his first month at the club, Mertesacker started in every one of his available league and European matches since his summer move, battling on through the month with various defensive partners as injury problems mounted. "I want to do a good job, especially in the defence," he said. "That is my role. If the coach praises me then that is a great thing but I have to go on and keep on working." In November, he enjoyed a positive month at the heart of the Arsenal defence as he developed his partnership with fellow defender [[Laurent Koscielny]]. The Germany international helped the ''Gunners'' to victories against [[Sunderland A.F.C.|Sunderland]], [[Stoke City F.C.|Stoke City]] and [[Chelsea F.C.|Chelsea]] – and was outstanding as Arsenal kept a clean sheet in the away victory in [[Olympique de Marseille|Marseille]]. He remained an integral part of [[Arsène Wenger]]'s first team, playing in every one of Arsenal's available Premier League fixtures over the next month. He was virtually ever-present over January, missing only the [[FA Cup]] victory over [[Leeds United F.C.|Leeds United]] through illness.<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=20 May 2012|title=Mertesacker and Arsenal work| date = 21 May 2012 | publisher = Arsenal}}</ref>

In February, Mertesacker suffered an ankle injury in the win over Sunderland away at the [[Stadium of Light]] and faced a long-term spell on the sidelines. Prior to his injury, he featured in the draw at [[Bolton Wanderers F.C.|Bolton Wanderers]] and the 7–1 victory over [[Blackburn Rovers F.C.|Blackburn Rovers]] at [[Emirates Stadium]]. "Unfortunately he has had surgery and we have lost him for a while," said Arsène Wenger. "How long, I don't know. He had reconstruction of his ligaments. So it will be long term." He had not featured for Arsenal for the remainder of the season.<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=30 May 2012|title=Mertesacker injury rules him out until season end| date = 1 June 2012 | publisher = Arsenal}}</ref>

In his second season, Mertesacker played in Arsenal's first two matches, helping the team keep clean sheets against Sunderland and Stoke. "I think we have a better situation than last year," he said. "The team is full of characters, good players and every position [has competition]." He featured four times in September, forging a fine partnership with [[Thomas Vermaelen]] (who replaced Koscielny due to injury) in the process. The German centre back was named man of the match after an excellent performance in a 1–1 draw with [[Manchester City F.C.|Manchester City]] at the [[City of Manchester Stadium|Etihad Stadium]].<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=18 September 2012|title=Mertesacker praised for Varmaelen partnership| date = 19 September 2012 | publisher = Arsenal}}</ref>

In October, Mertesacker continued to perform well, making four appearances and helping the club to victories over [[Norwich City F.C.|Norwich City]] and [[Queens Park Rangers F.C.|Queens Park Rangers]]. Laurent Koscielny praised the German's performances, saying, "I am happy for Per because he's a nice guy, very important in the dressing room. He's a joker so he's good for the team. I'm happy because he's played well this season and it's good for the team."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=20 October 2012|title=Koscielny approves of Mertesacker| date = 19 October 2012 | publisher = Arsenal}}</ref> Mertesacker was an ever-present throughout November. He scored his first goal for the club in the 5–2 win over [[Tottenham Hotspur F.C.|Tottenham Hotspur]] and was voted man of the match for his performance in the 0–0 draw with [[Aston Villa F.C.|Aston Villa]]. "It was amazing from the very start," he told Arsenal after the Tottenham game. "It was very good to score because we were one man up and they were dropping off. I kept standing in the box and tried to be lucky. The ball from [[Theo Walcott|Theo]] [Walcott] was very good and it was a good day to score."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=20 November 2012|title=Mertesacker scores first Arsenal goal| date = 21 November 2012 | publisher = Arsenal}}</ref>

Mertesacker made five appearances in December, missing only the trip to [[Olympiacos F.C.|Olympiacos]] in the [[2012–13 UEFA Champions League|Champions League]] and the home win over [[Newcastle United F.C.|Newcastle United]]. On being drawn against Bayern Munich in the [[2012–13 UEFA Champions League knockout phase|Champions League round of 16]], he said, "We will face a good team in Germany. They are top of their league and went through to the knockout stage in a phenomenal way. They only conceded seven goals in the first half of the season. [But] they have a little break now and can rest a bit. Maybe it's a good opportunity for us to face them in February because we will be in our rhythm. We will hopefully go through the Christmas period in a strong way. We can do that."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=28 December 2012|title=Mertesacker has faith in Bayern draw| date = 29 December 2012 | publisher = Arsenal}}</ref> Mertesacker captained Arsenal for the first time in the [[2012–13 FA Cup|FA Cup]] win over [[Brighton & Hove Albion F.C.|Brighton & Hove Albion]] in January, and appeared in every game save for the draw at [[Southampton F.C.|Southampton]] on New Year's Day. "We are always looking to win something and we can achieve something with this group," he told Arsenal. "We have a lively group so our thoughts are now on the next match. That's the most important thing for us, not what's going to happen in May. We have a few targets in our team that are possible this year. We won't talk about it, we'll just see what happens in the next few important weeks on the pitch."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=28 January 2013|title=Mertesacker says Arsenal targets are achievable| date = 29 January 2013 | publisher = Arsenal}}</ref> Mertesacker started four games in February, missing only the FA Cup loss to Blackburn at the Emirates. "It's always special to face a German team," the defender said ahead of the Champions League tie against Bayern. "[Me and [[Lukas Podolski]]] are looking forward to it because Bayern are a great team and are so consistent this year. It's a special game for German players to play against a team from their home country."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=25 February 2013|title=Mertesacker is looking forward to face Bayern| date = 26 February 2013 | publisher = Arsenal}}</ref>

[[File:Steven N'Zonzi, Per Mertesacker & Glenn Whelan.jpg|250px|thumb|left|Mertesacker and Arsenal against [[Stoke City F.C.|Stoke]] in the [[Premier League]]]]

Mertesacker was a mainstay in March, playing every single minute of Arsenal's four games. The centre back was on target in the defeat at Tottenham and was a key component in the defence that kept clean sheets against both Bayern Munich and [[Swansea City F.C.|Swansea City]]. "It rained cats and dogs, especially in the second half," he said after the win in south Wales, in [[Swansea]]. "It was very slippery but it was a vital win."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=25 March 2013|title=Mertesacker a vital component for Arsenal in March| date = 26 March 2013 | publisher = Arsenal}}</ref> In April, Mertesacker was shown a red card at [[West Bromwich Albion F.C.|West Bromwich Albion]] in the first game of the month. The defender returned to the team after suspension and was named man of the match against [[Fulham F.C.|Fulham]] after scoring the only goal away at [[Craven Cottage]]. "I think they've been terrific – not only defending very well but also creating goals for us at the other end like they did last week against Fulham," said goalkeeper [[Wojciech Szczęsny]] on the partnership between Mertesacker and Koscielny. "They're getting the credit they deserve because they work very hard and they're very honest lads. I'm very happy for them and it's much easier to play behind them when they are in that kind of form."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=25 April 2013|title=Mertesacker and Koscielny partnership noticed| date = 26 April 2013 | publisher = Arsenal}}</ref>

Mertesacker impressed at the back alongside Koscielny in May. The German defender was given the captain's armband in Arsenal's last game of the season when [[Mikel Arteta]] went off injured. "I think it is good for us to play against teams who are under pressure," he said after the win against Queens Park Rangers [who were on the brink of relegation]. "It helps us keep our focus on a high level."<ref>{{cite web |url=http://www.arsenal.com/first-team/players/per-mertesacker |access-date=16 May 2013|title=Mertesacker relishes pressure games| date = 17 May 2013 | publisher = Arsenal}}</ref>

On 12 April 2014, Mertesacker scored an 82nd-minute equalising goal for Arsenal in the [[2013–14 FA Cup|FA Cup]] semi-final against [[Wigan Athletic F.C.|Wigan Athletic]]. The match finished 1–1 after [[Overtime (sports)|extra time]], with Arsenal winning 4–2 in a [[penalty shoot-out (association football)|penalty shootout]].

After healing from injury, Mertesacker remained a mainstay in the Arsenal backline, playing alongside Laurent Koscielny. With Arsenal making a charge towards the title, Arsène Wenger singled out Mertesacker for praise, calling him an "important leader in the dressing room and a respected one".<ref>{{Cite web|title = Mesut Ozil and Per Mertesacker are Arsenal's leaders, says Arsene Wenger|url = http://www.skysports.com/football/news/11670/10141973/mesut-ozil-and-per-mertesacker-are-arsenals-leaders-says-arsene-wenger|website = Sky Sports|access-date = 25 January 2016|date = 24 January 2016}}</ref> On 24 January 2016, in a match against [[London]] rivals Chelsea, Mertesacker was sent off after 18 minutes for a late tackle on [[Diego Costa]], who later scored the only goal of the game at Emirates.<ref>{{Cite news|title = Chelsea's Diego Costa wounds Arsenal after Per Mertesacker's red card|url = https://www.theguardian.com/football/2016/jan/24/arsenal-chelsea-premier-league-match-report|newspaper = The Guardian|date = 24 January 2016|access-date = 25 January 2016|issn = 0261-3077|language = en-GB|first = David|last = Hytner}}</ref>

However, he would sustain an injury against [[RC Lens|Lens]] in the 2016–17 pre-season, undergoing knee surgery in his native Germany later that month. Following a clash between Arsenal and [[Viking FK|Viking]], [[Arsène Wenger]] confirmed that Mertesacker would be absent until December.<ref>{{cite news|url=http://www.arsenal.com/news/news-archive/20160805/wenger-on-transfers-and-individuals|title=Wenger on transfers and individuals|date=5 August 2016|work=Arsenal.com}}</ref> Despite the injury he was named club captain following the retirement of Mikel Arteta.<ref>{{Cite web|url=https://www.arsenal.com/news/news-archive/20160811/-our-new-captain-was-the-natural-choice-|title=Our new captain was the natural choice|website=www.arsenal.com|language=en|access-date=30 October 2017}}</ref> He was a second-half substitute on the last day against Everton.<ref>{{cite web | url = https://www.bbc.com/sport/football/39912025 | title = Arsenal 3–1 Everton | website = BBC Sport | date = 21 May 2017 | access-date = 22 May 2017 | first = Phil | last = McNulty}}</ref> On 27 May 2017, Mertesacker made his only start of the season, in the FA Cup final against [[Chelsea F.C.|Chelsea]], which Arsenal won 2–1.

Arsenal would later confirm the 2017–18 season would be Mertesacker's last, before becoming the head of the club's academy the following year.<ref>{{cite news|url=https://www.arsenal.com/news/mertesacker-lead-arsenal-academy|title= Per Mertesacker to lead Arsenal academy |date=7 July 2017|work=Arsenal.com}}</ref> On 7 January 2018, Per Mertesacker captained the Arsenal team in an FA Cup game away against Nottingham Forest and scored a goal to make the score 1–1, with the game eventually finishing 4–2 to Forest, before featuring in his last ever game for the club in a win against [[Burnley F.C.|Burnley]] on 6 May 2018.

==International career==
In September 2004, [[Jürgen Klinsmann]], then-manager of [[Germany national football team|Germany]], called Mertesacker up for 9 October 2004 game against [[Iran national football team|Iran]]. He made his debut less than two weeks after his 20th birthday when he came on as a second-half substitute for [[Christian Wörns]].
[[File:FIFA WC-qualification 2014 - Austria vs. Germany 2012-09-11 - Per Mertesacker 03.JPG|250px|thumb|right|Mertesacker during a [[2014 FIFA World Cup qualification (UEFA)|2014 World Cup qualifying match]] against Austria]]

With his quiet but effective game, he established himself as Germany's first-choice centre back,<ref>{{cite news|title=Hannover? Das bedeutet sehr gute Stimmung|url=http://www.haz.de/Nachrichten/Sport/Fussball/Uebersicht/Hannover-Das-bedeutet-sehr-gute-Stimmung|publisher=Hannoversche Allgemeine Zeitung|date=1 September 2009|language=de}}</ref> pairing up with [[Robert Huth]], [[Christoph Metzelder]], [[Heiko Westermann]] and later [[Arne Friedrich]]. At the [[2005 FIFA Confederations Cup]] hosted on home soil, he played the full 90 minutes in all five games and scored his first international goal in a group stage match against [[Australia men's national soccer team|Australia]] as Germany finished in third place.<ref>{{cite news|title=Buoyant Germans glimpse future|url=https://www.fifa.com/tournaments/archive/tournament=101/edition=8503/news/newsid=17537.html|archive-url=https://web.archive.org/web/20071031055233/http://www.fifa.com/tournaments/archive/tournament=101/edition=8503/news/newsid=17537.html|url-status=dead|archive-date=31 October 2007|publisher=[[FIFA|fifa.com]]|date=30 June 2005 | access-date =17 September 2010}}</ref>

At the [[2006 FIFA World Cup|2006 World Cup]] on home soil, Mertesacker paired with Metzelder in central defence. After Germany won the quarter-final penalty shoot-out against [[Argentina national football team|Argentina]], Mertesacker suffered minor injuries to his thigh and a kick to the groin when he was attacked after the final whistle by Argentine unused substitute [[Leandro Cufré]]; Cufré was later fined and suspended four matches. After Germany's loss to [[Italy national football team|Italy]] in the semi-finals, Mertesacker had surgery on one of his legs and left testicle (not related to the attack above, but an injury he had been dealing with during previous matches) and missed the third place play-off. Nevertheless, his impressive showing did earn him a transfer to Bundesliga team Werder Bremen after the tournament.

Mertesacker was first-choice when fit during [[UEFA Euro 2008 qualifying Group D|2008 European Championship qualification]] and was ever present in the [[UEFA Euro 2008|final tournament]] itself. Due to injury problems at the beginning of the 2009–10 season, he missed several [[2010 FIFA World Cup qualification (UEFA)|2010 World Cup qualifiers]] but later retained his place as first choice. Mertesacker regularly wears the number 17 jersey.

Mertesacker was called up for the [[UEFA Euro 2012|2012 European Championship]] but spent the whole tournament on the bench as an unused substitute due to the emergence of youngsters [[Mats Hummels]] and [[Holger Badstuber]].

==Outside football==
In November 2006, Mertesacker established the "Per Mertesacker Foundation", initially to support the family of his former Hannover and Germany late teammate [[Robert Enke]], who had just lost his young daughter several months prior. After Enke's suicide it began focusing on providing support for those suffering from depression and has since expanded to include disadvantaged and marginalized children, particularly those from immigrant backgrounds, in his native Hanover. Since 2007, the foundation has organised yearly charity football matches which have featured Mertesacker's national and club teammates [[Philipp Lahm]], [[Lukas Podolski]] and [[Tomáš Rosický]], as well as comedian Oliver Pocher, [[Fury in the Slaughterhouse]] member Rainer Schumann and German ice hockey legend [[Uwe Krupp]].
