I was following until you dropped that gem about French. Oh wait. Rafa won US Open without Federer or Federer's back was injured at Wimbledon and Nadal won. Oh wait. That does not count. Because Roger's injuries were real and Nadal's were fake, right?
Unlike Fed in RG, Nadal won Wimbledon twice so which one are you talking about?
Also, Federer never had an injury as serious as Nadal's injury last year, when Federer clearly benefited to win his only FO title and lucking out against Acasuso, Haas and Del Potro. That was the lowest tennis level ever showed to win Roland Garros. Everyone knows Nadal was the best on clay last year and he only lost/Fed won because he was injured.
Nadal has won at least 2 Slams on 3 different surfaces. Federer´s only Slam on clay happened with an injured Nadal and struggling to beat average claycourters in the process. Federer still needs to prove himself on clay.
