again the arrogance of Federer fans. It's not a "sure thing" that Nadal wins the French Open. Federer is playing at his level on clay, and clearly can beat him any time they meet on clay now, although he hasn't in the past.
However, after a 5 hour match in which Federer was in control for much of the match -- improving on his performance at MC -- it's really arrogant to say Nadal can't lose the French Open (lets forget about all the Hamburg complications).
Btw, I happen to think that the point about Nadal should stay out of Hamburg, but I think Federer should stay in it. There are advantages and disadvantages to everything. I think for Nadal, the advantage to playing in Hamburg -- keeping his rhythm, maintaining competitiveness, etc, all of that stuff -- is outweighed by the advantage of resting.
I think for Federer, the extra comfort that he could get by playing in Hamburg, the extra refinement he could add to his game, outweighs the tiredness factor. Of course, some would argue he can do that without being in Hamburg, but eh.
