Lol at people writing Wawrinka would beat prime Nadal in RG 2015 final. Against 2015 Nadal he would have won, but not against any other version. Today's final showed the difference. Djokovic in 2015 was playing low balls to Wawrinka's backhand which is pretty much the ideal position for Wawrinka and he was able to dictate all the points. Nadal on the other hand was hitting high topspin balls, and Wawrinka was forced to defend too much, something he hates to do. This is the reason why Wawrinka couldn't up his level like he did in 2015. Nadal is just not Djokovic on clay.
