Rublev defaulted and defending champ Medvedev knocked out in Dubai semifinals

Rublev is an absolute disgrace to the game of tennis and should be banned from the game. Abusing and swearing at a linesman shows the sort of pond scum Rublev is.

Just another example of a sociopathic Russian.

Question is : was the ball in or out ?

Was there a real mistake ?

Question is : was the ball in or out ?

Nope.

The question is : how long should this Rublev disgrace be banned for.

Laver, Sampras, Federer - and the rest - all were on the wrong side of 50/50 line calls. Yet never, EVER got in the face of a linesman and abused and swore at him.
