Martín Gastón Demichelis (born 20 December 1980 in Justiniano Posse, Córdoba) is an Argentine footballer who plays as a centre back for Bayern Munich. He was also a defensive midfielder before Ottmar Hitzfeld chose to employ his defensive prowess more as a center back. Career Demichelis started playing professionally in 1998 at Buenos Aires based club River Plate, but he did not manage to find himself a spot in the starting line-up until 2001. He had some good performances at River Plate, which resulted in a transfer to FC Bayern Munich in 2003. His first season with the German team was not very positive, because he suffered a number of minor injuries, but under the command of coach Felix Magath, he has found a place in the team's starting line-up. Martín has also played a vital role for Bayern in winning their two consecutive doubles in 2005, and 2006. On 11 September 2007, he scored his first international goal in a friendly match against Australia, in which his header proved to be the winning scoreline 1-0. Honours
