Roger Federer has responded to the betting allegations against him. At a press conference in Shanghai, he stated that,
I know it's 100% not true, so I'm pretty relaxed about this. ...the last thing I would do is harm the sport and create a negative light on our sport, so its disappointing someone is throwing my name around. ...I have nothing to hide and I'm sorry for those that think there is something to destroy but there is nothing.
He starts to discuss this at about minute 6:10.
