Kaflnikov merciless with Swiatek: "All you do is complain!"

Iga Swiatek's recent comments on the WTA calendar have caused a stir in the tennis world. While the Pole has repeatedly complained about the overloaded schedule that tenniswomen and tennismans have to cope with, some have found it hard to accept the criticisms exposed by the world number 1.

This was particularly true of Ivegueni Kafenlnikov, former world No. 1, whose comments quickly went viral.

Clearly very annoyed, the Russian expressed himself on social networks in a message that was probably too aggressive for the situation: "Is someone pushing you to play? All you do is complain!

I'll tell you what you deserve! You deserve to be paid a lot less than you're getting now! What do you think?"
