Fed blew it big time. I felt he'd lose in straight sets but not this easily.
In my opinion he started off very nervous and cautious when he needed to get off to a flyer. If you look at Monte Carlo and even more so, Hamburg, he came out all guns blazing ready to take on Nadal. He eventually lost those matches because he could not hold on to the lead but at least he had a lead! I think maybe he was trying to pace himself, but it didn't work and he never had an easy service game.
From the moment he walked on court he looked scared. I now feel that after losing to Nadal so many times his mind will be gone against him on any surface. I think Roger has harmed himself by continually getting to claycourt finals and losing to Nadal. If he'd lost here in the 4th round I'd give him a better chance next year rather than losing to Nadal again. Also you can't keep on making finals. Don't think he'll win the French now, but someone (most likely Djokovic) will benifit from Nadal losing one day at Roland Garros.
Nadal played some great tennis, but to be honest I've seen him play better against Federer in the other finals, he just didn't have to be at his best, but on evidence of previous form this tournament, he had plenty more gears.
