The fastest footballer on earth

Manchester United defender Rio Ferdinand is taking the world's fastest man up on his idea of turning his feet to soccer.

"If you want that trial at Man Utd shout me, I'll speak to the boss!! Well done in 100m, waiting for you to smash the 200m now!" Ferdinand told Usain Bolt via Twitter.

The Jamaican world record holder had told the British tabloid 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 be the fastest player in the team, but I can play as well."

Bolt is in London at least through Thursday, when he will race for his second straight Olympic gold in the 200-metre final to go with the two 100-meter golds he now has.

If the Man U manager  needs to see what he's like on the pitch, Bolt has posted a video of himself  playing pick-up soccer in Jamaica right before the Olympics. Bolt posted videos earlier of him meeting Man U players and of him kicking around a soccer ball with his coach.
