Manchester United goalkeeper Ben Foster accepts he'll have to stand down as soon as Edwin van der Sar proves his fitness.
Foster kept a cleansheet on debut in Saturday's win at Derby and said: "I wouldn't have thought the manager would have too much of a dilemma.
"Edwin's probably going to be fit for the Bolton or Liverpool game, and I've no qualms about him going straight back in.
"He's been fantastic this season, and if I were him I'd be pretty disappointed if someone came in for one game and took my spot."
