Tennis Star Daniil Medvedev Has Epic Meltdown On Umpire During Australian Open

I thought all the Russians were on the eastern Ukrainian border. What did I miss?

What a wanker

That ump is about to crap his pants.

I would have said, "bitch, shut the frick up."

Sakkari would get it.

I don’t mind the impassioned Mendeved. But, he comes off as such a whiner. Any way, is anyone watching this farce of a tournament which left out the world’s number 1 player?! AO is done until Novak can come back.

So it's not allowed in tennis for a coach to relay instructions to a player? If not, why?
