Dietmar Johann Wolfgang "Didi" Hamann (born 27 August 1973) is a German professional footballer who was most recently manager at Stockport County. He is currently playing for German amateur side TuS Haltern.
Throughout his career, he has played for Bayern Munich, Newcastle United, Liverpool, and Manchester City primarily in a defensive midfield position. He also spent time at Milton Keynes Dons as a player/coach before joining Leicester City as a first team coach. He was a member of the German national side from 1997 until 2006 and represented his nation in two FIFA World Cups and two UEFA European Championships, reaching the 2002 FIFA World Cup Final. He is known in Ireland as a football pundit on Raidió Teilifís Éireann's live coverage of major European and International competitions.
Throughout his playing career Hamann gained a reputation for being a highly consistent and reliable player. He is highly respected by supporters of Liverpool due in large part to his involvement in the club's victory in the 2005 Champions League Final.
On 5 July 2011, Hamann was named as the new manager of Stockport County, replacing former manager Ray Mathias. He resigned from the post on 7 November 2011 after only four months with Stockport struggling in 17th place in the Conference Premier citing failure of a proposed takeover by Tony Evans.Close
