Bolt to play at Old Trafford

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 said Tuesday.

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 funds for the United Nations Children's Fund, Unicef.

Bolt comes straight into the team as captain, with Williams leading out an England side in opposition.
