Murray admits mistakes cost him dear

Andy Murray was at a loss to explain why he was unable to present Roger Federer with a tough challenge as the Swiss won in straight sets in their second group match at the ATP World Tour Finals.
The No. 5 had beaten Robin Soderling in a hugely impressive first match on Sunday, but looked out of sorts as Federer sailed to a 6-4 6-2 victory in in little more than an hour. Murray failed to win a break point and won only eight points on Federer's serve.
"I got off to a bad start in both sets, which doesn't help. I returned poorly, served poorly. Against him, that's not going to win you the match," Murray said.
"I felt okay from the back of the court, not unbelievable, but there were quite a few good rallies. Normally I get myself into a lot more of them against him."
Murray had won his last two encounters with the six-time Wimbledon champion playing aggressively and taking the game to Federer, but this time he was unable to execute his gameplan as he would have liked.
"I didn't feel tight," he continued. "I tried to play quite aggressive. You're not going to hit winners every single time you go on the court. You're not going to play your best match every time. You're going to make a few more mistakes sometimes.
"Last time I played against him, it worked well. Today I made more mistakes than normal. When I went behind, I didn't put many returns in the court, I didn't put any pressure on his game. Therefore, the pressure obviously builds more onto you."
