- ATP World Tour Finals
Murray won't shy away from challenge

Andy Murray has vowed to go on the attack when he takes on Roger Federer in the ATP World Tour Finals on Tuesday.
The duo started their O2 campaigns with victories on Sunday, Murray easing past Robin Soderling and Federer disposing of David Ferrer. Murray is aware that a win would all-but guarantee his place in the semi-finals and he holds an 8-5 winning record over the former world No. 1.
He has gone on the front foot against Federer in the past and feels that is the best way to approach the match with the 16-time grand slam winner.
"When I played Roger and Rafael Nadal the last few times, I played very aggressive tennis," the Scot said. "That's what you need to do against them. Every time you play against him, it's tough.
"If I feel like I have to attack, then I'll attack more. If I feel like I can play like I did yesterday and win, then I'll play like that."
Murray was in fine form against Soderling, but is aware the win over the Swede will be a distant memory by the time he steps on court against Federer.
He said: "It's a new day. I played great yesterday. I could play horrible tomorrow. So I need to make sure I practise well and give myself the best chance to play well. If I do that, I'll have a chance of winning."
