Roger Federer and Rafael Nadal
Roger Federer! He has won 16 grand slams thus far, the most in th history of tennis. <3
Roger Federer in 2009. Rafael Nadal in 2010.
Yes. Over the past two years it has only been Rafael Nadal who has stopped him in the French Open. However Nadal has a long-term, persistent ankle injury which is effecting his speed and power around the court. Roger Federer continues to improve on clay and I see him winning it if not this year, then next, and with it the career Grand Slam. No, not after Wimbledon 2008. Roger Federer is going through a major slump although he doesn't admit it. Meanwhile, Nadal is becoming better and better. On August 18 2008, Nadal will become No.1 in tennis.
