Kyrgios was a commentator for Eurosport during the Australian Open, which gave him a front-row seat to all matches there. He saw Sinner play up close and was amazed by what the Italian managed to do in the semi-final against Novak Djokovic.
He was even more inspired by Sinner's performance in the final against Medvedev, especially considering how badly he started. The Australian, who is currently away from the sport due to injuries, talked about Sinner's performance and predicted even more success in the coming months.
"Jannik Sinner, what an effort. It was incredible how much his level raised in the third, fourth and fifth sets. He found his forehand. I’m just so happy that I was a part of it and could call it."
"I was there calling his matches towards the end of the year, against Novak in Turin and then at the Davis Cup. I thought that this guy was going to ask some serious questions and was soon going to be knocking on the door."
Sinner's success at the Australian Open didn't surprise many who followed him closely in the previous weeks, such as Kyrgios. He's been trending in the right direction for a while, and this was just the crowning moment for him.
"I saw the improvement on serve and elsewhere, and the maturity he has at such a young age is something that I never have, or had, to get over the hump."
"I did predict that he was going to be a new Slam winner in 2024 - whether or not it was this one, it could have been the US Open. This is going to be such a big leapfrog for him, and I think we’re going to see him win plenty more Slams in the next couple of years."
"Now he’s got this one, he’s going to be unstoppable. He shows incredible maturity. He has just won the biggest title of his life, and he’s very humble and giving me compliments. That gives you an insight of how he is."
