Nick Kyrgios has fired another dig at world number two Jannik Sinner following a comment about Andy Murray.
Sinner dominated his rival Carlos Alcaraz in the Six Kings Slam final in Riyadh, Saudi Arabia, winning 6-2, 6-4.
As it was an exhibition event, the result will not count towards their official head-to-head record or ATP ranking points, but it offered Sinner some revenge after losing to Alcaraz in the US Open final.
The pair have established themselves as the dominant forces in men's tennis, sharing all four Grand Slam titles this season.
Their rivalry has led to comparisons with the 'Big Three' from the previous generation: Novak Djokovic, Rafael Nadal and Roger Federer.
In a recent interview with Univers Tennis, former French star Jo-Wilfried Tsonga made his own comparison.

"For now, there are only 2 of them.”
Kyrgios quickly took to social media to agree with the Frenchman, replying on X with a one-word response: "Facts."
The Australian has been a vocal critic of Sinner in the past, particularly following the Italian's doping suspension earlier this year.
In February, Sinner accepted a three-month doping ban after two positive tests for the banned substance clostebol in March 2024.
He claimed the substance was taken unintentionally during massage therapy by his physiotherapist.
Kyrgios dismissed that explanation during The Changeover podcast earlier this year.

"Do you really believe he's going to hire a physiotherapist who carries a scalpel without a cover in his bag, accidentally cuts himself with it, and then gives him a massage without protection?
"He pays hundreds of thousands of dollars to that person and puts all his trust in him.
Kyrgios continued: "Tennis players like Sinner are super strict with everything and very professional, they don't even take a sip of alcohol, they take maximum care of themselves.
"Am I supposed to believe he knew nothing about the physio's situation? Come on.”
While the Big Three dominated tennis for over a decade, Tsonga admitted that he found Murray the hardest opponent to face, winning just two of their 16 matches.
Tsonga said: "He plays the right shot, generally speaking as a player, he sure did. He was often able to block me, pretty fine tactician.
"When I got going and really turned on the power, even then, he was able to find spots that would shut me down.
"So naturally it’s him who bothered me a lot."
