The Italian played a pretty fascinating match to take down Djokovic in the Australian Open semi-final. The 22-year-old will contest the final against Daniil Medvedev, and it might be the crowning moment of everything he has worked for so far in his life.
Kyrgios is in Melbourne watching it unfold, and he had some really good words to say about the Italian.
"He's just always willing to learn and get better. I've been keeping my out on him for the last year or two and he deserves all the success that's going to come his way and I'm sure that we're gonna see him in many more finals. That's for sure."
Speaking about the success of Sinner Down Under, Kyrgios also mentioned Darren Cahill and all the work he did since joining Sinner's team.
"Darren Cahill's a great coach, the changes that he's made in his game and the willingness for Jannik Sinner to give it a try has now elevated him to the top of the sport. No one has beaten Novak here in so long and in that fashion as well. Novak didn't even create one break point."
The Australian also compared Sinner to Djokovic, calling him the new Djokovic. He does think the Italian's rival, Carlos Alcaraz has the X factor, though. Ultimately, it will be interesting to see how the careers of both unfold.
"I just love the fact that Sinner compared. I love that comparison. He’s like him and Novak play similar. I can see it. After today, I definitely think that Sinner could be the new Novak. I mean [Carlos] Alcaraz obviously he's got that X factor maybe a little bit more flamboyant with his game style but Sinner is solid."
