Schalke 04 Lehmann started his career in the 1988–89 season with
Schalke 04, playing for them for nearly a decade. His first years were rocky, notably a game against
Bayer Leverkusen in 1993 in which he conceded three goals and was substituted after 45 minutes, causing him to flee the stadium alone by tram rather than taking the team bus, but Lehmann gradually established himself as a strong keeper lauded for his ability to intercept crosses. He scored his first league goal on 12 March 1995 in a 6–2 victory over
1860 Munich in the 84th minute, scoring Schalke's sixth goal from the penalty spot. His second goal was a last-minute equaliser scored against bitter rivals, Borussia Dortmund, in the
Revierderby on 19 December 1997. Lehmann became Schalke's team hero in their
1997 UEFA Cup Final victory over
Inter Milan, after playing a strong season and saving an
Iván Zamorano penalty in a
penalty shootout.
AC Milan Lehmann left Schalke for
AC Milan in 1998, but his performances were below par. In one game
Gabriel Batistuta scored a hat-trick against him, including a goal from a free kick in the box which Lehmann had conceded by handling a back pass. In another game he was substituted after giving away a penalty. After just five matches, Lehmann was dropped. Believing he wouldn't get another chance at Milan, he left during the winter.
Borussia Dortmund In early 1999, Lehmann returned to Germany to play for
Borussia Dortmund replacing long-time goalkeeper
Stefan Klos. Lehmann had a difficult start there after several poor performances. Rumors arose that Lehmann might leave, with supporters viewing him critically. But the tide eventually turned and Lehmann's form improved, becoming a reliable figure in the team. He played a significant part in the club's return to the upper echelons of German and European football. Borussia Dortmund began the 2001–02 season strongly and eventually won the
Bundesliga in
2001–02. That same year, Borussia Dortmund reached the UEFA-Cup final, though the team lost to Dutch club Feyenoord Rotterdam. Around this time, Lehmann developed a reputation for his poor disciplinary record. In a match against
SC Freiburg, Lehmann kicked opposing attacker
Soumaila Coulibaly after they collided in the penalty area. Lehmann was suspended afterwards. He currently holds the record for most red cards for any Borussia Dortmund player, and the record for most red cards for a goalkeeper in the German Bundesliga. Lehmann's form slipped in the 2002–03 season, along with Borussia Dortmund's. His time at Dortmund was winding down, and after the season concluded, he left Dortmund. He was replaced by
Roman Weidenfeller and
Guillaume Warmuz, who had just left Arsenal.
Arsenal 2003–04 season Lehmann joined
Arsenal on 25 July 2003 replacing the recently departed
David Seaman. Arsenal's 2003–04 season was historic. The Gunners finished the
2003–04 FA Premier League season unbeaten, becoming the first English club to accomplish the feat in the modern era and only the second to ever have an unbeaten season in English football's top tier, the only other team to accomplish this feat being
Preston North End in the 1888–89 season. Lehmann played every match in Arsenal's unbeaten season, though his swashbuckling playing style did lead to occasional mistakes. For example, in the title-winning match at local rivals
Tottenham Hotspur, Lehmann pushed Tottenham striker
Robbie Keane as the pair waited for a Tottenham corner. He also committed an error that led to the equalising goal in Arsenal's Champions League defeat at home to Chelsea the same season. Despite these mistakes, Lehmann's addition to the Arsenal team had a major effect on Arsenal's ability to finish unbeaten. And Arsenal continued unbeaten until 24 October 2004. At the end of his first season at Arsenal, he had already played 54 times earning himself a
Premier League winners medal.
2004–05 season By the middle of the
2004–05 season, Lehmann's inconsistent form lead to Spaniard
Manuel Almunia starting in several matches instead. However, Almunia made a series of mistakes during several games, thus allowing Lehmann to regain his position. At the end of that season, as speculation again began to mount that he would be replaced over the summer, Lehmann cemented his position in the Arsenal goal with a man-of-the-match performance against Manchester United in the
2005 FA Cup Final. He made several important saves and demonstrated great positional sense to keep the score 0–0 after
extra time, and then crucially saved
Paul Scholes' shot in the penalty shootout, which Arsenal won 5–4.
2005–06 season Lehmann had an outstanding
2005–06 season with Arsenal, making his 100th Premier League appearance for the club in their game against
West Bromwich Albion on 15 April 2006. He was a key factor in his side's first-ever accession to the
Champions League final; during their run Arsenal broke the record for the most consecutive
clean sheets in the Champions League with ten, breaking the record of seven that Milan had set just one year before. That run formed the bulk of an 853-minute spell without conceding a goal, overtaking the CL record for an individual goalkeeper set by
Edwin van der Sar.
Bayern Munich's
Hasan Salihamidžić had been the last to net against Lehmann, in the 64th minute of a last 16 first leg match on 22 February 2005; Lehmann kept a clean sheet in the second leg, and then a further seven during Arsenal's run in 2005–06 (Almunia played in the other five matches in the group stages). The final clean sheet was earned in the semi-finals against
Villarreal, after Lehmann saved an 89th minute
Juan Román Riquelme penalty. In the
final against
Barcelona, with the score still goalless, Lehmann was sent off in the 18th minute for a
professional foul after bringing down
Samuel Eto'o, making him the first player and – so far – only goalkeeper to ever be sent off in a Champions League/European Cup final. Arsenal would go on to lose 2–1 despite having the lead at half-time, but that did not stop him from being named the Champions League Goalkeeper of the Year for the 2005–06 season after going 853 minutes without conceding a goal.
2006–07 season His remarkable run was finally ended on 13 September 2006 by
Hamburger SV's
Boubacar Sanogo, who scored a consolation goal in the 89th minute of Arsenal's first group stage match of the
2006–07 Champions League season. Lehmann's contract at Arsenal was due to expire in summer 2007 and during the
2006–07 season there was much speculation he would leave the club on a
Bosman transfer. However, it was reported on 26 April 2007 that he had signed a year's extension on his contract, tying him to the club until 2008.
2007–08 season In the first league game of the 2007–08 season, Lehmann made a serious error after just 52 seconds, allowing
David Healy to score for
Fulham. However, Lehmann's blushes were spared late in the game as Arsenal won 2–1. In his second league match against
Blackburn Rovers he fumbled a
David Dunn shot to allow Blackburn to equalise, in a game that finished 1–1. On 24 August, the BBC reported that he returned to Germany to treat an
Achilles tendon injury which he picked up during international duty against
England, meaning
Manuel Almunia took his place for Arsenal's third match. Lehmann subsequently had to wait nearly four months to make another competitive appearance for Arsenal, which came in their final Champions League group match against
Steaua Bucharest. Nearly one month later, he played only his fifth competitive game of the season for Arsenal, against
Burnley in the third round of the
FA Cup; meanwhile third-choice goalkeeper
Łukasz Fabiański was selected for the
League Cup games. Lehmann expressed frustration at being number two to Manuel Almunia fearing it could cost him the number one jersey in the Germany national team for
Euro 2008. However, Arsenal manager Arsène Wenger described Lehmann's attitude as "super-professional". On 26 January 2008, Lehmann appeared in Arsenal's second FA Cup game of the season, keeping his second successive clean sheet as Arsenal beat
Newcastle United 3–0. Manager Arsène Wenger later promised Lehmann that, if he stayed at Arsenal, he would play every game in the FA Cup. On 29 January, Lehmann suggested that he will stick with Arsenal until his contract expires at the end of the season. Lehmann gave his reasons as his relationship with the fans, players, family situations and his chance to still be able to win things at the club; believing he "wouldn't have had this chance somewhere else." On 2 February, following an injury to Almunia, Lehmann returned in goal for Arsenal in the Premiership for an away fixture against
Manchester City, more than five months after his last league appearance; Arsenal won the match 3–1. Due to Almunia catching flu straight after the injury, Lehmann kept his place in goal for the following three matches in February, including the first leg of the UEFA Champions League round of 16 against Milan, but also the 4–0 loss to arch rivals Manchester United in the FA Cup. After another injury to Almunia in early April 2008, Lehmann was back in goal for the away game against Manchester United on 13 April 2008. Arsenal lost that game 2–1, virtually ending their Premier League title hopes for the season, their third consecutive season without a major trophy. There was speculation that would be his last game for Arsenal, but on 19 April, Lehmann played in the home game against
Reading, which Arsenal won 2–0. The following week, Łukasz Fabiański was given his Premier League debut against
Derby County and Almunia returned to the bench for the game. However, Lehmann made another appearance and was brought on for Fabiański in the last 20 minutes of the game against
Everton on 4 May, Arsenal's final home game of the season. He was given a standing ovation after the match as he bowed and clapped to the fans. Later that day, Wenger confirmed that it was Lehmann's farewell appearance.
VfB Stuttgart In early June 2008, it was announced that Lehmann had signed a one-year contract for
VfB Stuttgart. He joined the team's pre-season training on 24 July 2008, and made his debut for the club on 30 July 2008 in a friendly match against former team Arsenal. His competitive debut for the club came on 10 August 2008 in the first round of the
DFB-Pokal, a 5–0 away victory over
FC Hansa Lüneburg, and his Bundesliga debut one week later in Stuttgart's 3–1 away victory at
Borussia Mönchengladbach. On 3 April 2009, Lehmann extended his contract at VfB Stuttgart until the summer of 2010 and in August 2009, he announced that he would retire on 30 June 2010.
Return to Arsenal On 14 March 2011, German tabloid
Bild reported that Lehmann was in talks to come out of retirement, due to an injury crisis at Arsenal leaving them with only one fit senior keeper,
Manuel Almunia. Lehmann was also scheduled to spend six weeks working on his coaching badges at his old club. Due to the injury of Arsenal goalkeepers
Wojciech Szczęsny,
Łukasz Fabiański and
Vito Mannone, on 17 March 2011 Lehmann signed for Arsenal on a rolling contract until the end of the season. Lehmann was named as a substitute in Arsenal's match against
West Bromwich Albion on 19 March 2011. Despite newspaper reports that he might replace Almunia, due to the Spaniard's poor performances, Lehmann made his first appearance in
Arsenal's reserves on 29 March 2011 against Wigan, when Arsenal lost 2–1. On 10 April 2011, Lehmann started for the first team in an away game against
Blackpool. He was forced to start the game when Almunia was injured in the warm up. Winning 3–1, it was his 200th appearance for Arsenal. Lehmann became the oldest player to play for Arsenal in the Premier League but not the oldest to play for the Gunners in all competitions, a record held by
Jock Rutherford. Lehmann's contract with Arsenal expired at the end of the season, and then he decided to retire once again. On 8 September 2018, a match was organised between Arsenal legends and Real Madrid legends in which Lehmann appeared after
David Seaman picked up injury during training. He eventually made two saves in the second half and then saved a shot from Alfonso in the subsequent penalty shoot out. Arsenal legends won 5–3 on penalties, with Lehmann scoring the last penalty for Arsenal. ==International career==
