Campbell has impressed for Tottenham this season and Sir Alex insists he will bring him back from his loan move at the end of the season.
“Fraizer will come back here, there is no question about that,” said Ferguson.
“The idea for him was to get some experience, so it has been good for him in that respect.
“He has produced some fantastic performances for Tottenham and I am delighted for the boy because he is going to be a good player. His future is here.”
