Nick Kyrgios certainly knows how to stir up Novak Djokovic, but an Instagram post about the Serbian star referencing Roger Federer's emotional retirement has seen him run afoul of fans.
The 26-year-old Wimbledon finalist was one of thousands of people across the globe to pay tribute to Federer, who made his last professional appearance playing doubles at the Laver Cup alongside longtime rival and friend Rafael Nadal.
'SAD TO SEE': Tennis fans react to Rafa Nadal development
In one of his posts on Instagram though, Kyrgios couldn't help but throw a little jab at his old sparring partner in Djokovic, despite the seemingly renewed respect between the pair.
"Novak knows his chance for slams is better now. Rafa is shattered," Kyrgios posted, accompanying the touching image of Federer's farewell with a tearful Nadal in the background.
Tennis fans fumed over Kyrgios' comment, with many claiming it struck a disrespectful tone given the celebration of Federer's achievements.
His comment was an odd one, considering the farewell at the Laver Cup was Federer's sole tour appearance this year after encountering difficulties in recovering from a long-term knee problem.
Federer's renowned 24-year career, in which he won 20 grand slam titles, came to an end alongside Nadal in emotional scenes at the Laver Cup, with Djokovic also spotted tearing up at one stage.
Kyrgios was slammed for his 'audacity' over the post, which left some fans gobsmacked.
"Can’t believe he has the audacity to say this!!! It was such an emotional evening and he thinks saying this is appropriate honestly, what an idiot," one fan posted.
Who is psychologically able to write that? Okay okay/ to be fair, Djoko had a year full of controversy, so I can understand where people are coming from. BUTTTTTTTTTTTTT, I really do think that this person doesn’t understand tennis outside of the courts🎾#FedalForever https://t.co/DFhModhDn8

The Swiss legend was unable to bring the curtain down on his illustrious career with one final victory, after he and Nadal suffered defeat at the hands of Frances Tiafoe and Jack Sock.
Federer saw his 'dream' finale ruined in a 4-6 7-6 (7-2) 11-9 loss to dampen the spirits of fans at the O2 Arena in London.
The 41-year-old broke down in tears as he embraced his European teammates, including long-time friend and rival Nadal.
However there were staggering scenes when Nadal also burst into tears while sitting alongside Federer.
The Spanish champion appeared to feel the full weight of the emotional scenes as he wept into his hands while Federer farewelled the sport that has given him so much.
"It's been a perfect journey," Federer said as he again cried during an on-court interview.
"I would do it all over again. It's been a wonderful day. I told the guys I'm happy, not sad.
"I am so happy I made it through. The match was great and it's been wonderful.
"Having Rafa here and all the legends - Rocket (Rod Laver), Stefan Edberg - thank you."
Team World's first Laver Cup triumph denies Federer fairytale
Frances Tiafoe proved the pantomime villain for a second time at the Laver Cup when his epic comeback against Stefanos Tsitsipas denied Roger Federer one final trophy before retirement.
A 1-6 7-6 (13-11) 10-8 victory for the US Open semi-finalist, in the 11th match of the Ryder Cup-style team competition, helped Team World to their first triumph at the fifth time of asking.
Tiafoe saved four match points against Tsitsipas and his remarkable win took John McEnroe's team to the magic 13-point mark on a dramatic and thrilling Sunday at the O2, where they claimed a maiden Laver Cup by a 13-8 scoreline.
It was Tiafoe who teamed up with Jack Sock on Friday night to beat Federer and Nadal in an emotional doubles contest which brought the curtain down on the Swiss legend's glittering career.
Going into the third and final day of the competition, Federer still had hopes of adding one more title to his illustrious CV with Team Europe leading 8-4.
Felix Auger-Aliassime had other ideas for Team World, however. After success over Andy Murray and Matteo Berrettini in the doubles alongside Sock, he followed it up with an even better display in the second match.
Auger-Aliassime stunned Novak Djokovic 6-3 7-6 (7-3) to claw Team World back from the brink to put them one win away from silverware.
It was over to Tiafoe to complete the job, but he lost the first set in 21 minutes to Tsitsipas.
The Greek could not maintain his charge, though, and after a marathon tie-breaker for the second set, it meant a decider was required.
During the 10-point tie-breaker, Tiafoe held his nerve to help Team World make history.
Tiafoe reflected on-court: "Unbelievable, unbelievable feeling. Our captain Jonny Mac was tired of losing. I kept saying all week that this is our year. Guys showed up. Felix beat Novak, Jack and Felix also played unbelievable doubles and it wasn't just me.
"We all showed up. I just kept going and this is big. We'll celebrate big tonight."
