But Red Devils chief Sir Alex Ferguson has ruled out the switch and now Campbell has set his sights on a starting role.
"Now I'm back at United the plan is to try and force my way into the first-team plans," Campbell told the Daily Star.
"It was great going away with the first-team squad. I've had some good games and really enjoyed myself but now it would be good to get pre-season out of the way and start scoring goals."
He added: "I'm going to work hard and try to do enough to stay here and go on from there."
