but who will be there pushing him then? Federer has Nadal & Djokovic as an obstacle. Djokovic will have most of the folks already in the game who mentally disintegrate against him. Yes, Djokovic has this unbelievable ability to make you play an extra shot which is an asset that may decline, but I'd put more of a wager of Djokovic winning another 5 majors in the next 2-3 years than Federer winning another in that time. Federer's will be 40+ by then. He needs to win the immediate US & AUS to get a buffer because I think he's done after that.You think he's going to be moving like that in his mid 30s? There'll be a natural decline in his ability to play so defensively all the time. It's happened to Federer, it's already happened to Nadal... he's no exception.
