Usain Bolt set for Old Trafford charity match
Bolt, 31, retired from athletics in August 2017 having won eight Olympic gold medals and been crowned world champion 11 times.
But on Sunday he tweeted to say "I've signed for a football team! Find out which one this Tuesday at 8am GMT."
The Jamaican, who is a huge Manchester United fan, has always insisted he had "a chance" of becoming a Premier League footballer and had undertaken trials with German Bundesliga giants Borussia Dortmund and South African team Mamelodi Sundowns.
Excited to announce that I will be playing in @socceraid for @UNICEF_uk 2018 at Old Trafford on Sunday 10th June. Make sure you're ready @robbiewilliams! pic.twitter.com/t2sDB1iLP8
