A better player doesn't necessary means he will win most of the time, and one of the main reason is match up problem. Never in the history of tennis I find Nadal has so many advantage over Federer. Not just because he's a lefty, but his unique style that suits perfectly against Roger's style. Added to the fact this era also suits Nadal with the heavy ball, high bounce and slower court. Does anyone find any player in the past that possess such huge match up issues like Roger and Rafa? I can't see any past great players has this problem, at least not even close to this level.
