Manchester United goalkeeper Ben Foster admits he gaffed in the club's first friendly against Malaysia on the weekend.

"Coming on in a game is always a bit more difficult for goalkeepers than starting but that was particularly disappointing," said Foster, who had replaced Edwin van der Sar at the interval.

"I got a bit of stick from the lads that's for sure.

"It was just one of those things. I wasn't paying enough attention and took my eye off the ball.

"I have to make sure that kind of thing doesn't happen again."
