Nadal can't work on grass.. he doesn't have the game for grass. Grass and Clay are total opposites... paspas kaayo ang bola sa grass compared sa clay kay hinay kaayo. Big serves, solid net game and semi-flat grounds are what works on clay.. Nadal doesn't have this (he has high bouncing loopy grounds, his serve is decent but not great, and he can't rely on his net game) pero Federer's game is great for fast courts.

Footloose, I don't think naglisod si Federer sa Clay... Nadal is simply better sa clay. Federer's game works on clay pero he can't help it if someone else is simply wayyyy better than him on that surface. I think he reached a few finals this year sa Clay diba?
About sa French Open final... I don't think na discourage si Federer, he lost confidence pero wala ma discourage, he kept on fighting .. he even broke back on the 4th set while Nadal was serving for the match I think. He broke back and forced a tie-break. Nadal was just too good, he was retrieving winners and making Federer make an extra shot. It got to a point na Federer was raising the margin of error, going for risky low-percentage shots to force a winner.. pero it turned into unforced errors instead. He had so many chances to break back... there was one time nga love-40, then another time love-30, pero wala ka convert.
