Focused Federer hunting Olympic gold
Roger Federer is revelling in his status as favourite for singles gold at the Olympics, but is aware of the fine margins that split victory and defeat.
Federer will head into the event on a high having claimed his 17th grand slam title with victory at Wimbledon earlier in July.
The Swiss master is at home on the grass of SW19, but unlike Wimbledon the rounds leading up to the final will be best of three sets, as opposed to the best of five of grand slam events.
Any slips could be punished in the early rounds, which is something Federer is aware of as he limbers up for his opener with Alejandro Falla.
"I do believe winning Wimbledon will help with my confidence, it's been a great couple of weeks, and I don't mind being the favourite because that is when I play better," he said.
"However, at Wimbledon we play seven matches, all best of five sets, but at the Olympics we play five matches and only the final is best of five. If these rules had applied at Wimbledon I would have lost in the third round because I was two sets down.
"The margins are very small at the Olympics and a few points can change a game, we're also playing singles and the early rounds can be dangerous."
