German international Lehmann originally signed for Arsenal from Bundesliga side Borussia Dortmund in July 2003 and went on to make 200 first team appearances for the Gunners.
During his first spell with Arsenal, Lehmann, played in every match of the Club's unbeaten league campaign in 2003/04, when he was awarded the Premier League Golden Glove Award for his integral part in the ‘Invincibles' season.
As well as winning the Premier League title in 2003/04, Lehmann won the Community Shield in 2004 and also an FA Cup winner's medal in 2005, when he famously saved from Paul Scholes in the victorious penalty shoot-out.
Prior to joining Arsenal in 2003, Lehmann was a Bundesliga title winner with Borussia Dortmund in 2002, and UEFA Cup winner with Schalke in 1997. He also had a brief spell with AC Milan in 1998.
Lehmann was a regular fixture for the Germany national team for a decade, making 61 appearances for his country. Before retiring from international football in 2008, Jens was a member of the Germany World Cup squads in 1998, 2002 and 2006, in addition to their squads for the European Championship Finals in 2000, 2004 and 2008.
After leaving Arsenal at the end of the 2007/08 season, Lehmann moved to German club Stuttgart, where he spent two years before announcing his retirement from football at the end of last season.
He rejoined the Club a short-term basis in March 2011 during the time in which keepers Wojciech Szczesny, Lukasz Fabianski and Vito Mannone were out through injury.
Lehmann made one appearance during his three-month spell back in north London, helping Arsenal to victory at Blackpool.
