The way he is playing right now is awesome, if he keeps it up he will do that.
Making TMS finals and Barcelona final best of 3 sets laso helps a lot. so far he isn't tired at all at Monte Carlo , also burnout is not a real possibility he can skip Hamburg if he wins Rome to recharge before French Open last year he made it playing more sets finals including that marathon in Rome and still look strong in Paris he had some hard matches (especially against Mathieu) but was never in postion to losing at RG , in fact he wasn't in danger of losing match at RG since his first victory.
Is comeptition stronger this year ?? I don't think so
1.Almagra hasn't imporved so much
2.Federer is in bad form he can peak but right now he is not Federer from year ago on clay courts
5. Davydenko totally off form
6. Robredo has no weapons to win a set with him
7. Canas plays the same game but Rafa is doing it many times better
OK Djokoivc can be hard but I still like Rafa chances on clay against Djoko espeically in best of 5 match
Berdych could be threat but maybe in Rome where courts play faster , no way on RG I don't see Berdych winning on clay with Nadal in best of 5 match
