Bolt told The Sun: "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.
"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 am in Britain for a few more days. If Alex Ferguson wants to give me a call he knows where I am."
Bolt declared himself "the greatest" after his triumph on Sunday evening.
