Roger Federer says he isn’t surprised that Novak Djokovic took down defending champion Rafael Nadal in the final of Wimbledon. New No. 1 Djokovic has only lost once this year.

"When you lose so rarely, your confidence carries you a long way,” Federer said at a Davis Cup press conference. "He's proved before at Wimbledon that he can play on grass. It's good for tennis that it happened."
