Everybody who tells the negative posters to shut up is just blind. Yes, we all support him whatever. But he hasn't been the same player since his surgery. And it's NOT now a factor - he's been saying since the French Open that he's felt OK physically. Either it's taken something away from his game or he's lost motivation generally. He's certainly lost confidence and concentration.
I think the game is there. He just seems to lack belief against these guys. The three tournament wins in 5 weeks was great, but he just collapses when he sees Federer or Djokovic.
