Re: Which of the following can be the biggest threat to Nadal at RG?
The sample of one particular match is too small to draw conclusions about Isner's chances against Nadal.
Besides, Isner was never close to win this match.
Closer than Fed thats for sure. Also before you come up with your shot at Monfils just remember he is the only guy to beat Fed indoors in the last 14 months.
Stronga,Monfils,DelPo,Nalbandian,Berdych,Gulbis,Ha as and Djokovic are the players I support the most.
