I saw the whole match, as well as the almagro match. They played the same way they did as in previous matches on their way to get to the semis/finals and they played nadal in the same form and Ferrer got killed and Almagro just disappointed. Ferrer looked like he was playing wiffle ball and nadal looked like randy johnson. Nadal is the favorite in a 5 setter. Whether you guys like it or not. I would love a change up at RG, but I still have doubts that an even injured nadal can be defeated unless someone is playing lights out like soderling did in '09.
Djokovc has got that capacity to play lights out though, and that's the reason many predict if anybody is going to knock Rafa out at RG it'll be him.
Del Potro has a slight chance, he grew up on clay and is capable of playing well up there, he also has played tight contested matches against Rafa on clay and grass before as well.
Apart from those 2, I don't think anyone's got a chance. Fed has proven he just cannot do it, Murray no chance, Tsonga doubt it, Berdych no chance, Ferrer and Almagro LOL, anyone else hasn't got much chance either.
Novak has only made it to one RG final though, so he will have his work cut out to make it there unless he's drawn to play Nadal in the quarters or semis.
Nadal's nightmare RG draw would be to face Novak in the quarters and if he wins that, then Del Potro in the semis (if Delpo can manage to get past Ferrer). If he can get through those 2, then he'll be taking number 8.
At the same time if he gets into Fed and Murray half, he'll most likely be making the final against Novak. After beating Fed and Murray, he'll be too tough for Novak imo.
