Foster, 24, played 90 minutes for the reserves on Thursday night after a 10-month absence and came through the match unscathed.
"I think that would be good for Ben and I will have a chat with him early next week.
"We have already had a few enquiries for him from the Championship and will consider these options."
"Everyone recognises that he is potentially the top goalkeeper England have available," said the United boss. "I think he is above them all.
"He came through the reserve game without any problems. We are very pleased, because he is a fantastic prospect."
