Jamaican sprint star Usain Bolt, an avowed Manchester United fan, could appear for the Premier League club in a charity game next summer, according to manager Alex Ferguson. \"Usain\'s a character and a big United fan,\" Ferguson told Inside United magazine of Bolt, fresh from his second successive triple gold haul at the London Olympics. \"But it\'s interesting he says he\'d like to play in a charity game. It could be brilliant, and next year when we play Real Madrid\'s Legends again, there could be opportunities to bring him up and see how he does.\" That game is scheduled for June 3, 2013, at Old Trafford, but comes in mid-season for Bolt ahead of several lucrative Diamond League meets and the August 10-18 world championships in Moscow.
