Murray: I don't fear Federer

Andy Murray insists defending champion Roger Federer holds no fears for him as he waits to learn his semi-final opponent at the ATP World Tour Finals.

Murray sealed his place in the last four at London's O2 Arena with a straight-sets victory over Jo-Wilfried Tsonga, finishing second in Group A behind world No. 1 Novak Djokovic.

The world No. 3 will face the winner of Group B - most likely Federer - on Sunday. With two wins against Janko Tipsarevic and David Ferrer, Federer has already secured his place in the last four, but could finish second behind Juan Martin Del Potro, if the Argentine beats him in straight sets on Saturday.

Murray may have to beat both Federer and Djokovic if he is to win the title in London - as he did when winning Olympic gold - and the Scot knows he will have to up his game to have a chance of winning his first title at the year-end championships.

"I think over the years, I got used to playing those guys a couple of times in a week," Murray said. "It's happened quite a few times.

"It's not something that I'm afraid of. I know it's incredibly difficult and challenging to beat guys like that back-to-back, but it's doable. But you're obviously going to have to play great tennis to do that, and I'm aware of that."

Murray beat seven-time Wimbledon champion Federer on grass in the Olympic final, and he admits he would rather face the Swiss on grass than indoors, where Federer has lost just once in his last 22 matches.

"He's played great indoors the last few years, that's for sure," Murray said of Federer. "I played him quite a few times indoors, had decent success against him early on. The last few times I played him, haven't done so well indoors. But his record speaks for itself.

"He's played very well so far here. Yeah, he likes the conditions when they're like this. It helps his timing. When he's timing the ball well, he plays great tennis. He's won indoors, he's won on grass, he's won on outdoor hard courts, and on clay. I don't know where I'd rather play him. I mean, I had good matches with him on grass this year, so I'd maybe say grass."
