I agree. His movement slowed considerably after he had his foot bandaged at the end of the 2nd set. It was clearly hampering him.
Still, Djokovic plays gruelling back to back 5 set matches and comes through (see 2012 AO semi and final) so clearly his fitness is superior to Murray's and everybody else on the tour.
