Pat Cash has delivered a scathing attack on countryman Nick Kyrgios following his win over Stefanos Tsitsipas at Wimbledon.
Kyrgios played Tsitsipas in the third round last week, with it being a feisty affair in which both players thought the other should have been defaulted.
Tsitsipas hit a ball into the crowd, with Kyrgios then badgering the umpire to default him.
Kyrgios, meanwhile, was given code violations for audible obscenities and was accused of 'bullying' and 'having an evil' side by Tsitsipas.
Cash, though, despite sharing a nationality with Kyrgios, has firmly sided with Tsitsipas.
“It was absolute mayhem, Cash said of Kyrgios while commentating for the BBC. "He was lucky to even get through the first set.
"He should have been defaulted in the first set. Something's got to be done about it. It's just an absolute circus.
“He's brought tennis to the lowest level I can see as far as gamesmanship, cheating, manipulation, abuse, aggressive behaviour to umpires, to linesmen,” Cash added.
“Is it entertaining? Yeah, possibly. It's gone to the absolute limit now. [It's] the gamesmanship, the abuse he was giving. Tsitsipas got sucked right into it.
"So it was entertaining and fascinating but, for me, it's gone too far now.
“I have no problems with a bit of gamesmanship but, when it gets to that level, I think it's just out of control.”
Nick Kyrgios has backed up that win over Tsitsipas by beating Brendon Nakashima on Monday to move into the Wimbledon quarterfinals.
Kyrgios will face Cristian Garin in the quarterfinals after he beat another Australian, Alex De Minaur. It was the first time in this year's tournament that a player has come back from two sets down to win a match.
