Djokovic must be at his best to top invincible Nadal in U.S. Open final
"No doubt that when you win a big match, the feeling is great," Nadal said. "Novak is a great opponent. It is true we already play a lot of important matches for our career, so that makes this confrontation special. When you have the chance to win against the most difficult players, is true that the victory is more special. But not in a final of the US Open. What really is important is to win the tournament, not the opponent."
