Roger Federer says that while he would like to win the Olympic gold medal in singles, he wants to try and enjoy himself in London rather than treat the event as a must-win situation. Federer failed to medal in singles at the last two Olympics. "I do feel less pressure...because I have won the Olympic gold in doubles already in Beijing with Stan [Wawrinka], and that was an amazing feeling and made me very proud to do that for Switzerland," Federer told reporters.
