Three words when ND is on top form: Ruthless, emotionless and flawless. When Djocovic is on top of his game, no one in the world can beat him in my opinion. Not even Federer 2007 or Nadal 2010. He is by far one of the best all court players I have ever seen, there isn't one flaw in his game. What I respect most is his will to win. So anyone think he can get a first open era 'Grand Glam' this year.
