England star Foster spent five years at Old Trafford as understudy to Edwin van der Sar before leaving for first-team action with Birmingham in 2010.
He said: "I've lost every time I've been back there.
"I got pumped 5-0 with Birmingham, then we lost 2-0 there last year.
"For every player it's special to play at Old Trafford, but with the way our team is I don't think anybody gets too excited about games like that.
"There are a lot of teams who go there like rabbits stuck in the headlights.
"They get star-struck by it all - but our manager Steve Clarke won't let any of us get like that."
