ATP AcapulcoZverev's Mexico disqualification 'not too harsh' says Djokovic40 MINUTES AGO “You need to control your emotions,” he said. “Of course, I'm not in favour of breaking racquets. But I can understand that you can break a racquet.

I did break racquets, and I'm not proud of it. I regret that. “I think what happened to Sascha is he totally lost his mind.

And it is different. If you go out there and break a racquet. That's not good, of course.

The moment where you react and feeling your anger, you just destroy the racket because you're not playing well. “When you are against the umpire, and you hit the racquet against the chair and try to smash the racquet you are insulting him/her. This is a line which you absolutely cannot cross.

“The good part is, of course, he's showing that he cares, caring about the doubles, which is good. «But this is absolutely off the wall, you cannot do that. And it's fine if sometimes you just go out there and complain about yourself.
