Nick Kyrgios has been fairly open in recent months about how he doesn't feel respected and has hit back about criticism saying that he brings eyes on the sport.
Kyrgios is set to face Novak Djokovic in a practice match highly dubbed on Friday and it sold out in under an hour.
Taking to Twitter, he jibed at those criticizing him including in his own country. "Wow Nick Kyrgios is bad for the sport! Wow what a disgrace, a national embarrassment! How dare he sell out another stadium, the arrogance."
He also responded to a fan telling him to be humble and let his play do the talking by saying 'nah I'm good'.
This match forms part of a practice schedule where fans will pay to enter the grounds and watch practice matches between the best with money going to charity.
