The controversial forward has admitted that he had the chance to move to Old Trafford twice in his career, but opted not to.
The former Manchester City man will be motivated to score against the Premier League champions, but has revealed that had things been different he could have worn the red of the Old Trafford outfit during his career.
Speaking ahead of the game, Bellamy has admitted that United enquired about his availability back in 2010.
"My adviser had a conversation with United in 2010, shortly before I came to Cardiff on loan," he told the Daily Mirror.
"It was great to feel wanted, and I would have loved to do it, but it was never going to be allowed.
"After Carlos Tevez had moved the opposite direction the year before, I didn't expect anything to come of it."
Bellamy went on to state that Sir Alex Ferguson was keen to sign him over ten years ago, when the Welsh forward was on Newcastle’s books.
"Actually, there was a link with Sir Alex as far back as 2002, when my representatives went to see him at United's training ground, with a view to a move going ahead," he added.
"But Newcastle had just qualified for the Champions League, I loved playing for Sir Bobby Robson and had just been offered a new contract there.
"To be honest, I used an inquiry from United to hold out for a better deal."
Bellamy scored a memorable brace for Manchester City in a 4-3 defeat at Old Trafford in September 2009, with Michael Owen scoring an injury time winner for the hosts.
Just how Bellamy would have fitted in at Old Trafford remains to be seen, as although he was talented when at his best, his career has been blotted with controversy.
Sir Alex Ferguson had a reputation for not putting up with players who he did not see eye-to-eye with, and a clash between the pair would have been inevitable had Bellamy signed for United.
At 34, Bellamy will look to make United suffer when the champions take on Cardiff this afternoon.
