The England Under 21 international striker was loaned to the London side on a season long loan deal as part of the the deal that brought Dimitar Berbatov to Old Trafford in the summer.
However, Fergie has revealed that United do have the option of recalling Campbell from the loan spell in January.
"We could pull him back in January," Fergie has said.
"We have the option and it is a possibility.
"He is a good player but we needed to get him first-team experience."
