I've heard a lot about many reasons why French players never were number 1 and have not won a slam for 30 years : all these reasons are true (the main one being that people maybe enjoy too much life in France
but frankly speaking, we've had players all having great qualities, but not all of them
Noah had everything except the technique.
Leconte had the greatest talent of all but had a bad physique.
Tsonga not good enough technique.
Monfils the same and not enough focused, etc ...
As for Gasquet, I like him but he's never had the potential some saw in him : technical, physical and mental lacks. Very good "racket touch" talent, maybe the best one, but Leconte had much better technical bases.
