While conversing with Nour and supervisor Roland Herfel, he shared,"If I tell him something bad, I get disqualified. But what am I supposed to tell to this guy? So you prefer that I retire? I'm giving my best effort. So why the hell is he not giving his best effort? Why are you deciding for me if I give my best effort or not? I'm not going to try to continue your role."He continued,"I want to do something bad. I'm not allowed to because I'm disqualified. Why is every referee in the world trying to intimidate me? I didn't say one word. After US open, I'm trying to be good."However, in an official statement from the Association of Tennis Professionals (ATP) to The Athletic, the tennis body admitted the violation was issued erroneously and Medvedev will not be fined.
