Foster is looking forward to the League Cup final against Tottenham on Sunday.
“It is a good opportunity to win a medal,” Foster told The Daily Mail. “If I do play, it will be absolutely fantastic.
“All the lads are buzzing. Those who are in contention cannot wait for it to come. It would be a special day for me if I could play in it and win it. Sunday could be a bit of a stage for me to remind people of what I am about.
“When I finished at Watford I had a little bit of a reputation as a decent up-and-coming goalkeeper and in the last couple of years because of circumstances I have faded away almost.
“It is a good chance to get my name back out there and people can see that I am still around and still a good goalkeeper.”
He added: “To play on Sunday would be an unbelievable bonus and a massive up for me. It has been heartbreaking to watch United win things when I cannot be involved.”
