On Monday, 2012 Olympic 100-meter champion Usain Bolt told a British newspaper that he'd like to play for Manchester United. On Tuesday, United star Rio Ferdinand offered to help, and the two exchanged tweets about the possibility. 

"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," Bolt told the Sun on Monday. "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." 

On Tuesday, Rio Ferdinand sent this tweet to Bolt: "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!" 

Bolt replied: "After the Olympics we work on that...lol..thanks man". 

Bolt won the Olympic 100 meters Sunday with a time of 9.63 seconds and advanced to the 200-meter semifinals Tuesday with a qualifying time of 20.39. 

The 6-foot-5 Jamaican first met United coach Alex Ferguson and the team when he visited Manchester in 2009 to take part in a 150-meter sprint through the city streets. 

"I would be the fastest player in the team -- but I can play as well," Bolt told the Sun. "I am in Britain for a few more days. If Alex Ferguson wants to give me a call, he knows where I am. I definitely want to see what I could do. I think I could step up to the Rooneys." 

A United spokesman told the Sun: "As the fastest man on Earth, he would undoubtedly add speed to the team."
