How many male players did achieve the golden slam yet? Djokovic will definitely go for it and make it. With Olympic gold in his back he is going to the US Open and will be unstoppable again. I can't see anyone seriously threatening his reign for at least the next two years to come.
no one yet, if he win both, he will be the first one, it is a rare opportunity, TBH, since Olympics are every four year
back on topic, Nishikori pulls out a nice win, and he is set to play Ivashka in next round, then Djokovic, match with Djokovic would be a good one few years ago, but at the moment, even home ground could not bring him any advantage, to even make that match interesting
Djokovic will play mixed-doubles as well, with Stojanovic
