Other than playing NADAL, FED has never done so much running!
No wonder instead of looking 31 vs Murray he looked 41. Fed has never been used to being jerked left to right except when playing nadal and we all know how that ends up. Now with Murray and djoker fed has to do this more regulary on a hardcourt clay and grass and he cannot handle it even if he was 23. At FO12 djoker beat him straight sets then in the Olympics after fed looked more refreshed he had no gas vs Murray and YES he wanted to win. It's one thing schooling tomic raonic and tsonga but against a fit nadal Murray and djoker unless grass on a hot day it's all she wrote.
