When asked about his next challenge, Bolt, who runs the Olympic 200m tonight in London, said he wanted to try out for Manchester United.

 “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 Sun reported Bolt as saying.

“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.”

A United spokesman said: “As the fastest man on Earth he would undoubtedly add speed to the team.”

This isn’t just a new dream for Bolt.

He hung out with Sir Alex Ferguson and the UNited squad in 2009 and in 2011 said: “I definitely want to see what I could do. I think I could step up to the [Wayne] Rooneys.”

Bolt has been delaying any partying in London until after the 200m final.

“The 100m is just one step in the door,”he said. “But now there’s the 200  m. I have to defend this one too; that’s what’s going to make me a legend. I’m looking forward to it.”

Then, perhaps, looking forward to a chat with Sir Alex.
