In upcoming episodes of Netflix’s tennis series Break Point, the 24-year-old took aim at the Australian star.

His heated words came in the wake of their heated showdown during the third round at Wimbledon last year when Kyrgios got the job done in a fiery four-sets.

During the contest the Canberra native requested his opponent be defaulted after he hit a ball into the crowd and appeared to hit someone.

The two men lobbed grenades at one another during their respective press conferences, accusing each other of being in the wrong during the explosive clash.

Tsitsipas has now reignited the ugly feud with fresh remarks in the wake of Wimbledon coming to light in new episodes set to air next week.

“He has brought that NBA basketball attitude to tennis. I would describe it as an uneducated approach of playing tennis. But you know tennis is a gentleman’s sport, it’s all about respect. We are not playing basketball. I feel he was trying to destroy my rhythm. He kept putting his towel in my box,” Tsitsipas said.

“There was zero respect coming out of my opponent that day. He kept pressing my buttons none stop – and of course I got annoyed. He just loves attention. And if he gets none of that, it is complete destruction.”

Tsitsipas swiped his rival on social media at the end of last year after Kyrgios withdrew from the United Cup.

Kyrgios pulled out of the mixed teams event on the eve of the inaugural tournament, to be held in Sydney, Brisbane and Perth.

Despite swirling suggestions Kyrgios had simply snubbed the event, Aussie great Wally Masur said on Thursday Kyrgios’ injury management was a very legitimate excuse.

Tsitsipas’ response to the news was somewhat different.

“It is not a surprise, I hope he enjoys his holidays,” Tsitsipas said in Perth.

The Australian star made an eye-opening revelation during the series when he stated he was admitted to a London psychiatric ward during Wimbledon in 2019, and was contemplating taking his own life.

He said 2019 was “the lowest point of my career” and he played the tournament with a white sleeve on one arm to hide evidence that he’d been self harming.

“I was genuinely contemplating if I wanted to commit suicide,” Kyrgios said.

“I lost at Wimbledon. I woke up and my dad was sitting on the bed, full-blown crying. That was the big wake-up call for me. I was like, OK, I can’t keep doing this. I ended up in a psych ward in London to figure out my problems.”

Kyrgios’ long-time manager and friend Daniel Horsfall said he was “f**ked” and the tennis star cried while telling him: “Bro, I don’t know what to do. I don’t want to be here.”

Kyrgios said he “hated the kind of person I was” and couldn’t deal with the expectation.

“I was drinking, abusing drugs, lost my relationship with my family, pushed all my close friends away,” he said.

“You could tell I was hurting. My whole arm was covered in scars. That’s why I actually got my arm sleeve. To cover it all.”

Part 2 of Netflix’s Break Point is set to air on June 21 while Wimbledon is set to get underway on July 3.
