Old Trafford was used as a venue for several matches in the football competition at the 2012 Summer Olympics. The stadium hosted five group games, a quarter-final and a semi-final in the men's tournament, and one group game and a semi-final in the women's tournament, the first women's international matches to be played there. Since 2006, Old Trafford has also been used as the venue for Soccer Aid, a biennial charity match initially organised by singer Robbie Williams and actor Jonathan Wilkes; however, in 2008, the match was played at Wembley Stadium.
