Man Utd keeper Foster hoping for Cup chance against Leeds
Foster lost out to Tomasz Kuszczak in the race to takeover between the sticks during Edwin van der Sar's absence.
But he is desperate to push his case for a regular starting spot if he is given the gloves today and for the midweek Carling Cup semi-final showdown with Manchester City.
Foster said: "It is always a big game against Leeds. The rivalry between the two clubs goes back a long way.
"I am hoping to be involved in this month's cup ties and I'm really looking forward to experiencing what his game is like to be involved in. Some people may think the competition has been devalued in recent years, but in my eyes the FA Cup is a very special trophy.
"It has got the great tradition of big teams coming up against lesser-known team from lower divisions and there are usually shocks along the way. That is the beauty of it.
"We then have another big cup match coming up on Wednesday. Like the fans, the lads are really looking forward to these ties. It is a great way to start 2010.
"People will obviously be talking about the derby earlier in the season during the build up to the game. But I'm not sure how much bearing that will have on the tie. The result (United won 4-3) will have hurt City and they might want some revenge, but the bottom line is City always want to beat us and vice-versa.
"Hopefully we can produce a good performance at City as we'd love to get to a final again because we want to defend the trophy. Getting to a final always gives everyone a boost."
