Currently watching Djokovic, he looks fine despite the injury he had in the last match.
If he manage to win this match, his next opponent is Wawrinka, one of the few players that makes the serbian sweat.
Federer looked ugly in his first two matches but today he did it well, let's see how things go against Goffin.
As for Nadal, i think Chung will be a good opponent to test him since the first round was meh and didn't play the second one because his opponent retired.
As for the ladies, as always everything is up to Williams, if she's fine the rest has nothing to do, but there is the possible rematch against Osaka, the controversial final of last year
