Man Utd veto loan move for keeper Foster
Although Edwin van der Sar remains sidelined by a knee injury, Foster appears to have slipped down the United pecking order as Tomasz Kuszczak has been in goal for four of the five games the Old Trafford side have played since the Dutchman has been out.
The mere suggestion brought a sharp response from Ferguson.
"Nothing is going to happen with Ben," said the United boss.
"He is here and this is where he stays."
The Scot also confirmed he was still waiting for Van der Sar to decide whether he will extend his stellar career by another 12 months.
At 39, the former Holland star knows he cannot continue forever. However, he will be given the chance to remain at Old Trafford if he wishes to stay.
"Edwin usually comes to us around this time and tells us what he wants to do," said Ferguson.
"It generally comes in the form of a telephone call from his agent to (chief executive) David Gill, but we have not received it yet.
"At the moment Edwin has an injury but it is not serious and he could be ready for next week."
