In the spirit of coming up with realistic ideas on how Federer can beat Nadal read on; Feds forehand is awesome. But the one drawback of any right handed forehand is that they cannot defend against left handed opponents who hit to their backhands. Nadal exposed this weakness by relentlessly hitting hight topspin shots to Feds one handed backhand. Fed tried to counter by running around his backhand as much as possible but it just didnt work. If fed developed a left handed forehand I think Nadal would be in some very deep trouble....even on clay.
