Djokovic even though he made all the way to the final is not playing good.He already lost 13 games on his serve he is very aggresive and nervous and that is not god especially not in game like this where their serve is going to be their main power and their serve can won the game.Federer had no troubles so far he is playing calm and good and should not have troulbes against Nole who allready prooved that he is not stable.
