Since 2012, I think Djokovic has worked on his volleys, and now they are noticeably better. Probably on par with Nadal, and definitely better than Murray. I heard a commentator say the same thing in their match in Shanghai. This has to be bad news for Murray, because volleys used to be the only thing that he did better than Djokovic, and now Djokovic does it better!! Do you agree?
