After reaching the semifinals of the Paris Masters where he fell to Novak Djokovic in three sets, former No. 1  Roger Federer says that he is pleased with the state of his game. The Swiss will face Djokovic again in their first match at the ATP World Finals on Tuesday night in London. Both men are in round robin Group B, along with Juan Martin del Potro and Richard Gasquet.

“I'm happy that I was able to keep playing after Basel. I played three three-setters [in Basel], and again here two three-setters,” Federer told reporters. “That’s a lot of tennis over the past 10 or 12 days and it’s given me a lot of information. I know what I have to do now, I know what I did well and what I can improve. I know where I am physically, and mentally I have a lot of confidence. I know my body is keeping up. I still have another week where I have to give it all. But now I know where I am.”
