He doesn’t know when to just be quiet and lay low. And maybe he thinks only talking to Serbian press won’t get out. He’s very wrong. Federer and Nadal probably have egos to rival his, but they have teams that manage them so much better. They choose their moments to speak and act, and they maintain a bit of distance and mystique appropriate for their massive level of stardom. He has the money to invest in a good team, but for whatever reason, chooses not to. Maybe it is ego. Again, he’s giving his haters so much ammo and making it harder for his supporters. A lot of players (most of the French ATP guys, Thiem, Schwartzman, et al) have spoken out in his defense, given that he’s friendly with them, but he’s doing them a disservice.
Focus on getting match-ready for USO and/or RG, dude.
