I agree that Nadal looked like he wanted it more but I think that Federer actually wanted it equally or even more. Watching his face and the way he was playing at times really reminded me of how sometimes when I'm tilting/running bad and I just focus on winning, I just want to win so badly that I don't even think about how best to play the game. I make careless mistakes because I can't take my eyes off of winning. It gets even worse if that frustration is directed at a particular opponent. Nadal has become a monkey on Federer's back, and it doesn't look like he will go away soon until Federer changes his mindset to view Nadal as just another opponent, with weaknesses to be exploited. Federer has been the calmest, coolest guy on tour for the past 5-6 years and it's really only against Nadal that he looks unfocused, which is a shame.

Federer is on the downslope, I agree, and Nadal looks like he will only get better for some time, but there are plenty of younger players who will begin challenging the top two. I do think, though, that if Federer can bounce back from this loss with a fresh attitude, he will surpass Sampras and be able to defeat Nadal a few more times, hopefully at Roland Garros. Sometimes a loss when you want a win so badly is exactly what you need to force you to step back, examine and retool your game, and come back mentally stronger.
