3). Nadal
Nadal is Roger's NEW Nalbandian, i don't see this kid as much trouble ... honestly. Roger played terrible tennis and nearly had him in a 5th set, until being forced to play in the dark ... which was unfair to him ... all excuses aside ... Nadal won "fair and square" , but the gap between Nadal & Fedex is small ... if there is one ... it's to Federer's advantage ... I don't see why many believe Nadal to be so much trouble for Roger ... they've played 1 time when he had heat stroke, another time on an extremely slow surface in Miami and in Paris, where Federer nearly took it to a 5th set even with 60 UFE ... if he cleans up his play and improvises his strategy on clay a tad bit ... possibly improve net play also ... why could he not dominate Nadal ? I just don't see it, I'm sorry. I know everyone wants to create a rival for Roger, but Nadal isn't the one ... he's a young Carlos Moya ... I'd still go with Roger ... ON ANY SURFACE against Nadal.
All of his Top Spin is a tad difficult for Roger to adjust to, but we know our Swiss friend loves a challenge and it's only a short period of time before he begins to dominate their "rivalry"
