well, Nole won 3 masters on clay but not RG. He needs to win RG. now, because Rafa is God on clay, and Nole won twice against him on clay, Madrid and Rome, Nole is better than Fed. too lazy to look at stats, but did Fed ever win on clay against Rafa except when Rafa played half dead in Hamburg?
well , rafa was ok in hamburg.
federer in rome 2006 for example and in other matches forced to the limits the best nadal on clay , and was when the masters were played with finals in 5 sets like rome 2006 , nole can defeat that nadal in 5 sets on clay??????? in all his 5 sets matches in clay nole only could won a set , and federer was capable to bagel that nadal on clay in some sets.
