Andy Murray crashed out of the ATP World Tour Finals after losing to a spirited Roger Federer 7-6 6-2 in an enthralling semi-final.

Federer overcome Murray in a close-fought first set, before dazzling the Scot with some scintillating tennis at the 02 arena to clinch the match. Murray admitted he was disappointed to lose, but reflected on a remarkable 2012 which saw him win both Olympic Gold and his first grand slam at the US Open.

"I would have liked to have finished, obviously, with a win. But, yeah, that didn't happen. But for me, it's been the best year of my career by a mile so why I would look back on that negatively now would be silly because I've achieved things I've never achieved before. I have to look back on it positively. If I don't, then that would be worrying."

Federer now meets world no.1 Novak Djokovic in tonight's final, as the Swiss looks to win a record seventh season-ending title. Federer said he expected tonight's game to be a fitting end to the year.

"Yeah, exciting. Look, no doubt about it, I love playing against Novak (Djokovic). He's had a great year. He's had a great tournament so far and he played another good, tough match today against Juan Martin, who had him in the ropes. So credit to him to really come back and win. For me, I think for both of us, it's pretty straightforward. I think we've got to press out the last juice that's left in our body and make it a successful year end, even though it's been successful for everybody who has been taking part in this tournament. But it is a big opportunity playing sort of the last match of the season, and facing off against Novak obviously is always special, especially here at the World Tour Finals."

Currently the top two players in tennis, Djokovic and Federer have won two games each in their four meetings so far this year. Federer will be the favourite after proving to be the master at playing indoors, but Djokovic will be eager to win to cap off another remarkable year at the top of the sport.
