No, Nadal is nowhere near clutch like RF. When he faced his true rival (according to his
diary book), he got whooped. He almost lost the RG final this year FFS. Next.
Djokovic, on the other hand, is a clutch player. He goes out of his comfort zone on MPs and pulls out ridiculous stuff time and again. If I saw it once, I'd call it luck. If I saw it twice, I'd call it unbelievable luck. He's done it too often for it to be a coincidence. Still, the lack of mental fortitude of the field today has also played its part.
not sure what you've been seeing during federer-nadal matches, but the fact that nadal is mentally stronger than federer helped him win those close matches
rome 2006, roland garros 2006, wimbledon 2008, australian open 2009
about the only close match federer won between them was wimbledon 2007
