"We had a crisis in the financial world and I also had a crisis -- I dropped to No. 2," Federer said, smiling.

"It doesn't matter to me," said Federer, the winner of a record 15 Grand Slams, including the last two at the French Open and Wimbledon. "I'm past that point. People try to hype it up, but I don't read anything into it. I know my game's on, and when my game's on, I know I can beat any player in the world."
