"I can't get a fine for that," Rublev calls for more tolerance from chair umpires

After qualifying for the round of 16 following his victory against Wong (173rd) at the US Open, Rublev once again faced his demons. Pushed to a fifth set, the Russian had to fight mentally to ultimately win 2/6, 6-4, 6-3, 4-6, 6-3.
Speaking at a press conference, the world number 15 discussed the behavior he sometimes displays on the court, particularly the insults he directs at himself. In his opinion, umpires should show more tolerance toward this:
"When I say negative things about myself, I'm the one deciding how to do it. I can't get a fine for that. If I had insulted the chair umpire, yes. If I had said it to someone or shouted it all over the court, yes, of course. The same thing happens to everyone in life, in crucial moments, in stressful situations.
I don't think we're saints or that we never swear in those moments. Either we joke, or we get angry, and sometimes it happens. As I said, if you do it to someone or if you do it too openly, yes, but with yourself, it's your decision."
For reference, the player had previously received a $3,000 fine for swearing during his match against Tristan Boyer.
