World No. 7 Tomas Berdych tells reporters that he has a chance to win the ATP World Tour Finals. Berdych will meet No. 1 Novak Djokovic in his opening match on Monday. "I'm not thinking, 'Do I need to be doing something different or not,'" said Berdych, who is 1-7 lifetime against the Serb. "If I bring my best game then I know every time I play [I can win]. When I was able to play my best tennis, I was able to beat all of those guys. I hope I can get to that level and then we'll see what's going to happen."
