World No.2 Jannik Sinner is optimistic that he will convince coach Darren Cahill to be with him for the next season. Sinner has taken his career to new heights under the Australian’s tutelage, and he wants to keep playing under his umbrella.
The Italian won two Slams in 2025 and qualified for the final of all four Majors in the ongoing season. After winning the Six Kings Slam, Sinner’s next assignment is the Vienna Open, which will begin on Wednesday.
“We haven’t talked yet, to be honest. We said we are going to finish the year, and then we might ask him for a long chat, trying to convince him,” Sinner told ATP Media with a smile on Monday. “But in any case, if he stays or not, he has been an amazing person and obviously a coach for me to hold the whole team together in the tough moments.
“He is like a second father to me, so I’m happy to have him here. It’s a huge privilege to work with him. We aim for something very positive [for him to stay], and I will need a lot of hope for that.”
Sinner had earlier revealed that 2025 would be the final year of his partnership with the Australian coach, who has been with him since 2022.
“The results have been amazing, so I will try to make it happen for my own well-being,” Sinner said when asked about convincing Cahill to stay. “So I need that. He’s been important because I see the effort he puts in, working with a 24 year old kid flying all over the world and putting in a lot of effort.
“He has family, he has many, many important things to do also off the court and managing this and always putting me basically in the first place, it has been amazing and I’m very sure we can, we can make something very positive.”
Sinner said he is grateful that he has had a great run in 2025 as he has ticked the right boxes on the court.
“I’m seeing my year as very high, winning two grand Slams and making the final in the other two biggest tournaments we have, winning Beijing recently,” Sinner said of his season. “The last week[s] were a great confidence boost and for me, most importantly, that the mental aspect is in the right way, in the right spot. I’m very happy and grateful for that. I feel good at the moment.”
Sinner will kick off his Vienna Open campaign against Daniel Altmaier on Wednesday.
