if he keep playing like this , Yes..i still think if he could convert those match points against Djokovic in USO semi, he could beat nadal
anyway , since Anacone came after wimbledon , we all see Roger is more aggressive and playing abit more like his oldschool tennis. and i think if he keep this level , he is going to win slams next year.
the best thing about Roger is he doesnt use energy as much as others do , he win by his tricks and mind games. and thats abig advantage
