Sunderland striker Fraizer Campbell admits he'll have mixed emotions returning to Manchester United tomorrow.
He said: "It will be a strange one going back and not being a Manchester United player, but you know after a while the time is right for a change of scene.
"I was with the club since I was 10 - more than half my life, which is a lot.
"It was a great education. I learned such a lot from being around top players, coaches and Sir Alex Ferguson, who was always around the training ground with advice. If I am involved, which hopefully I will be, I will be up against mates so I am sure it will be a bit strange.
"Being at Manchester United was great, but I asked myself if I was going to play enough games to be the professional I want to be. The answer was 'no' so I had to move on."
"I am a Sunderland player now and will be giving my best for my team tomorrow."
