Lol Nadal is nowhere near to close to beat Federer on grass.
Federer can beat Nadal on clay, providing he tunes up his game to Shanghai levels and sorts out his mental block. It seems that he intends to peak just before the French..
hey mate just remember last year's W?? rafa despite not being that good on grass but still got one set off fed and he could have won the 4th set too,to make it a very tough fifth-setter
so this year rafa will definitely improve on grass and next two years would be so so harder for fed to maintain his unbeaten record on grass!
