Djokovic's stamina is better than Andy's?? I seriously doubt that. His stamina is unreal, but have you seen how many times Djokovic looks like he's going to fall over and die?? Breathing problems don't help I suppose, but he does that way more than a top player should.
Andy's stamina is above everyones except for a top form Nadal who can last until the end of time and perhaps Ferrer.
Well then I guess Novak earns his wins over Andy thanks to his superior tennis skills. Andy just makes it close from time to time and has a solid head-to-head thanks to his "above everyones" stamina
OT, Novak in 3
