You are right, Nadal use his top spin forehand to go to
right-handed backhand to generate a weak response and then kill
them off. Damn predictable.
But give it your best shot..
Federer changed to combat this in the previous french open, by
trying to go down the line, going to Nadal's backhand so as to
negate. But Nadal using his speed, went around, and uses his
forehands instead.
tennis is a game of brains, skills, but most importantly
physique.
if you got speed, and power, you are 1/4 there already.
Rem, Nadal is a right-handed, but trained to use his left-hand for
tennis by his uncle. To me, that's talent.
