Usain Bolt 

Multiple Olympic champion Usain Bolt will line up opposite British pop star Robbie Williams in a charity football match at Manchester United's Old Trafford stadium, the Jamaican revealed yesterday. The now retired Bolt had given a teaser of what was to come on Twitter on Monday, claiming that he had signed for a football club and would reveal all 24 hours later. His new team is the Soccer Aid World XI — a motley crew put together to help raise money for the United Nations Children's Fund, Unicef. Not only has football-mad Bolt, the fastest man alive, been recruited for the match, but he is also named captain, with former Take That star Williams leading out an England side in opposition.
