As the season's Champions League top scorer with nine goals, the youngest in the tournament's history, Messi scored two goals and assisted two more to ensure a 4–0 quarter-final victory over Bayern Munich. He returned as a false nine during the final on 27 May in Rome against Manchester United. Barcelona were crowned champions of Europe by winning the match 2–0, the second goal coming from a Messi header over goalkeeper Edwin van der Sar. Barcelona thus achieved the first treble in the history of Spanish football. This success was reflected in a new contract, signed on 18 September, which committed Messi to the club through 2016 with a new buyout clause of €250 million, while his salary increased to €12 million.
