Here is the post I made when Novak faced Rafa on clay at Monte Carlo a few weeks ago. I thought Nadal was gonna come up with the victory, but Novak handled him 6-3, 6-3.

Along with Nadal being 70-1 at the French, he's also 93-1 all time in best-of-5 set matches on clay. It's just hard for me to see Novak losing with the way he's playing this right now. Seems like the only guy who's given him consistent trouble in the last year is Federer (4-4 in the last 8 matchups between the 2). Djokovic is on another level right now.
It's also tough to go against Nadal getting that kind of a number at Roland Garros. I'm not going to bet on it, I'm just gonna (hopefully) watch the match and enjoy it, because I do believe it has the potential to be a classic.
