Novak Djokovic said: "Federer, you know, we all know how good he is anywhere, but especially here. This surface complements his game very much. He loves to play very fast. Takes away the time from his opponent. Just doesn't give you any same looks.
He just rushes you to everything. So for players maybe like Nadal or myself that like to have a little more time, it's a constant pressure that you have to deal with."
