Per Mertesacker

Per Mertesacker (German pronunciation: [ˈpeːɐ̯ ˈmɛɐ̯təsʔakɐ]; born 29 September 1984) is a German football coach and former professional player who played as a centre back.

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. After various standout performances at Hannover, as well as starring for the Germany national team at the 2006 FIFA World Cup at age 21, he transferred after 74 league matches for Hannover to fellow Bundesliga outfit Werder Bremen, for a fee of €5 million later that summer. 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, and finished as runner-up in the 2009 UEFA Cup.

After earning praise at the 2010 World Cup, and with his contract at Bremen ending, he transferred to Premier League club Arsenal a year later, for a fee of £8 million. 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. He eventually built up a solid relationship with fellow defender Laurent Koscielny, and the duo starred as Arsenal ended their nine-year trophy drought by winning the 2014 FA Cup. He later captained and scored for the side in their retention of the trophy a year later, before becoming the club's outright captain in 2016. He again starred in his third victory of the trophy in 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 international level, Mertesacker played for Germany at the under-20 and under-21 levels, before debuting for the senior side in 2004 against Iran. Mertesacker established himself as Germany's first-choice centre back for ten years, participating in UEFA European Championship in 2008 and 2012, as well as the 2006, 2010 and 2014 FIFA World Cups, winning the latter. He retired from international football following the world cup win.

Mertesacker has developed other ventures, including the "Per Mertesacker Stiftung", a charitable foundation that helps support amateur sportsmen, and the poor. He transitioned into coaching following his retirement, taking charge of the Arsenal Academy.

The second of three sons, Mertesacker was raised in Pattensen, a small town on the outskirts of the city of Hanover. He began playing football alongside his brothers at the local amateur club TSV Pattensen before joining Hannover 96, where their father was a part-time coach. As a youth player Mertesacker was neither a highly regarded prospect or had any ambitions of being a professional footballer and chose to study for his abitur with the goal of entering tertiary education.

Mertesacker joined the youth system of Hannover 96 where he played under his father Stefan, one of the youth coaches, until age 15. While juggling his football commitments and training, he completed his 'Abitur' at Carl-Friedrich-Gauß-Schule, a comprehensive school located in nearby Hemmingen noted for its sports program, and subsequently carried out his 'Zivildienst' at a centre for handicapped people in Hanover. He was promoted to the first team for the 2003–04 season and made his league debut in November 2003, starting against Cologne in the unfamiliar role of right-back. At the time of his debut he was the youngest German-born player in the Bundesliga. However he had a forgettable match and was promptly substituted at half-time by veteran Steve Cherundolo and sent back to the reserve/amateur team. Mertesacker was not seen as an exceptional player at that time and had thought about changing sports. He returned to the first team during the latter half of the season and contributed to Hannover 96's successful battle against relegation. The following season began more auspiciously as he scored his first goal as professional, a last-minute equaliser against Borussia Dortmund in August 2004. Having established himself as first-choice centre back, his strong performances and clean disciplinary record did not go unnoticed by new national team coach Jürgen Klinsmann, who called him up and eventually handed him his senior international debut in October 2004.

The slender Mertesacker was soon dubbed "the Defence Pole" (die Abwehrlatte) by German tabloids and gained a reputation for his good disciplinary record. His first 31 Bundesliga matches ended without a single yellow card, earning him the nickname "Mr. Clean". He was only booked twice during his entire career at Hannover. On 13 May 2006, he played his last game for Hannover 96 and fittingly scored the opening goal in a 2–2 draw against Bayer Leverkusen.

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.

In October 2018, Mertesacker returned to Hanover for his charity-cum-testimonial match, which featured his former teammates from Hannover 96 facing off against a "World XI" team composed of his former teammates from Arsenal, Werder Bremen and the Germany national team. Instead of holding his testimonial match in London, where he was based when he retired, he chose Hanover as it was where his career began.

In August 2006, Mertesacker moved to Werder Bremen in a €5 million transfer deal after a highly impressive performance in the 2006 World Cup, in which Germany finished third. At the time of his transfer, he and Brazilian midfielder Diego, who joined from Porto, were jointly Bremen's most expensive signings in the club's history. 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 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.

The 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. Bremen finished runners-up in the league winning only two games fewer than champions Bayern Munich and managed to seal a place in the next season's Champions League. At the end of the season, he signed a two-year extension to his original contract.

After returning from the 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 UEFA Cup semifinal second leg against Bundesliga rivals Hamburg. 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 UEFA Cup final loss against Shakhtar Donetsk and 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 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 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.

In the 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.

On 31 August 2011, 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, Stoke City and Chelsea – and was outstanding as Arsenal kept a clean sheet in the away victory in 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 through illness.

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 and the 7–1 victory over 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.

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 at the Etihad Stadium.

In October, Mertesacker continued to perform well, making four appearances and helping the club to victories over Norwich City and 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." Mertesacker was an ever-present throughout November. He scored his first goal for the club in the 5–2 win over Tottenham Hotspur and was voted man of the match for his performance in the 0–0 draw with 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] was very good and it was a good day to score."

Mertesacker made five appearances in December, missing only the trip to Olympiacos in the Champions League and the home win over Newcastle United. On being drawn against Bayern Munich in the 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." Mertesacker captained Arsenal for the first time in the FA Cup win over Brighton & Hove Albion in January, and appeared in every game save for the draw at 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." 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."

In September 2004, Jürgen Klinsmann, then-manager of Germany, called Mertesacker up for 9 October 2004 game against 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.

With his quiet but effective game, he established himself as Germany's first-choice centre back, 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 as Germany finished in third place.

At the 2006 World Cup on home soil, Mertesacker paired with Metzelder in central defence. After Germany won the quarter-final penalty shoot-out against 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 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 2008 European Championship qualification and was ever present in the final tournament itself. Due to injury problems at the beginning of the 2009–10 season, he missed several 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 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. He broke his seven-year goal drought for the national team when he scored his second international goal for Germany on 17 October 2012, in a 2014 World Cup qualifier against Sweden. On 13 September 2013, he scored his third goal for Germany against the Faroe Islands. On 19 November 2013, Mertesacker captained the side and also scored the winning goal as Germany beat England 1–0 at Wembley Stadium in a friendly match to mark the 150th anniversary of The Football Association.

Mertesacker was announced as the new Arsenal Academy manager prior to the 2017–18 season, officially assuming the position in July 2018. He launched a coaching programme as part of the club's partnership with Save the Children in the Zaatari refugee camp to provide football pitches and training for coaches specifically in the area of detecting PTSD symptoms. After Unai Emery's sacking in late November 2019, Mertesacker took the role as interim assistant manager to support interim head coach Freddie Ljungberg for the meantime.

In broadcasting, Mertesacker first joined DAZN Germany as a pundit in 2018, covering the Champions League. He left DAZN in 2020 to join public broadcaster ZDF where he replaced the outgoing Oliver Kahn. Mertesacker appears as a pundit on their Euros, DFB-Pokal, Germany national team and Champions League final coverage, usually alongside former Germany teammate Christoph Kramer.

On 24 July 2026, Mertesacker was appointed managing director for sport of the German Football Association (DFB), effective 1 January 2027, assuming responsibility for the national teams and the DFB Academy.

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. T-shirts and sweatshirts bearing the words "Big Fucking German" – the Arsenal fans' chant for him and a play on the Roald Dahl novel The BFG – are among items sold to raise money for the foundation.

Mertesacker co-owns the Hanover-based real estate agency CP Immobilien GmbH with his Werder Bremen and national teammate Clemens Fritz. The duo started the business venture in 2012 while planning for their retirement.

At 1.98 m (6 ft 6 in), Mertesacker was commanding in the air but he was also sound in defending on the ground. He often used his strength to shrug opponents off the ball and his standing tackling ability to win balls. Despite being criticised by pundits for his lack of pace, he compensated with his excellent positional play and astute reading of the game. As a result, he was able to make clean interceptions and clearances, hence his reputation as a defender who rarely conceded reckless fouls or got booked.

Mertesacker possessed solid technique, was a good defensive organizer, and a neat distributor of the ball. He averaged 46.3 passes per game in 2010–11 season, the third highest in the Werder Bremen squad, and the second-highest pass success rate, at 82%. In the 2012–13 season with Arsenal, he averaged 50.1 passes per game with a 91.5% success rate, fourth-highest in the league. Often, Mertesacker was paired with a more mobile and quicker defender who could track-back in a counterattack situation, such as Mats Hummels and Arne Friedrich for Germany, Naldo at Bremen, or Laurent Koscielny at Arsenal.

Mertesacker met his future wife German international handballer Ulrike Stange in 2008 while both were recovering from injury at a rehab clinic in Donaustauf and began a relationship not long after. They married in June 2013 and have two sons (born April 2011 and May 2014). Mertesacker is a Protestant Christian.

In an interview with German newspaper Der Spiegel published in March 2018, Mertesacker admitted to suffering from anxiety attacks throughout his career due to the "inhumane pressure" to perform, but had continued on due to his love for the sport and the desire to win silverware, and expressed his relief that he would no longer have to experience it anymore as he was retiring. The well-publicised interview drew criticism from some current and former players but he was generally praised by many others, including professional sports psychologists and his former teammates, for his candidness and courage in broaching a sensitive topic and addressing the perception that footballers were "perfect". It reignited debate within Germany about the psychological welfare and well-being of professional footballers and elite athletes.
