"People think I am joking, but if Alex Ferguson called me up and said: 'OK, let’s do this, come and have a trial,' it would be impossible for me to say no," the gold medallist told The Sun.
"I would not take up the challenge if I didn't think I was good enough. I am a very accomplished player and know I could make a difference.
"I would be the fastest player in the team, but I can play as well."
Bolt warned Ferguson that any approach would need to happen quickly.
"I am in Britain for a few more days," said the fastest man on earth. "If Alex Ferguson wants to give me a call he knows where I am."
One United supporter said: "We definitely lacked a bit of pace up front last season. Fergie should seriously consider Bolt's offer. Having him zip down the wing could be the difference in next year's title race."
After Sunday's 100m glory, Bolt is hoping to defend his 200m title in Thursday night's final.
