Nadal's the best player in history on [clay], and he is one of the best-ever players that played this game.
I like my groundstrokes, I can say. I like it. That's my game - I'm a groundstroke player and I play pretty aggressive.
The confidence is there, the game is there, but physically you can't fight nature sometimes. You can't do much about it.
I don't think, that you can always - you can ever - get your game to perfection, you know. Only if you're Federer.
Tennis is a mental game. Everyone is fit, everyone hits great forehands and backhands.
