Foster was originally selected in Manchester United's squad for the 2008 FIFA Club World Cup, but after suffering a broken finger in training the day before the squad was due to depart for Japan, he was replaced by Ben Amos. On 1 March 2009, Alex Ferguson named Foster in goal for the 2009 League Cup Final at Wembley Stadium. After keeping a clean sheet in normal time, Foster then made a save from Tottenham's Jamie O'Hara in the consequent penalty shoot-out. This, combined with a miss from David Bentley, gave United a 4–1 win in the shootout and the 2009 League Cup title. After the match, Foster was given the Alan Hardaker Trophy for his man of the match performance.
