Nadal, Federer still on collision course

After a week of action at the French Open, the men's draw is playing out pretty much as expected. Federer is into the fourth round, and Nadal will play his third round match today against Lleyton Hewitt. Djokovic and Murray are also still alive, so there have not been any huge upsets so far. It looks like both Federer and Nadal will march straight to the final. I really can't see Djokovic or Murray or anyone else posing a threat to them. And I'm not sure Federer will be able to beat Nadal on clay. He's lost to him in the final here three years in a row, and right now Nadal looks unstoppable, not even coming close to dropping a set.
