Nick Kyrgios is back in action at Wimbledon on Monday after his dramatic victory against Stefanos Tsitispas as he closes in on a mouthwatering semi-final with Rafael Nadal.
The maverick Australian toppled Tsitispas in a heated four-set thriller on Saturday, during which he called for the fourth seed to be kicked out of the tournament for hitting a ball into the crowd.
Kyrgios called the umpire a "disgrace" as tempers frayed and the bad feeling spilled over into the post-match press conferences.
The defeated Greek player said his opponent has an "evil side" and described him as a "bully", comments that Kyrgios laughed off.
Kyrgios, 40th in the world, thrives on his bad-boy image and Saturday's outbursts were not even his first of the tournament.
But it will be a different challenge against American Brandon Nakashima, a player he has never faced before, and he may struggle to re-create the big-match intensity on Centre Court.
Kyrgios, who has only reached the quarter-finals of two Grand Slams, believes he has the firepower to win Wimbledon.
