Darren Cahill will continue coaching Jannik Sinner at least throughout 2026. The Italian made it clear throughout 2025, a year when the Australian initially planned to step away from the project, that he would try to convince him to stay for at least one more season.
For now, Jannik Sinner has achieved that goal. It remains to be seen whether he will persuade Darren Cahill to continue in a team where, along with Simone Vagnozzi, they have managed to transform a slender, powerful young player with little physicality into a number one, improved physically and with a variety of skills that go beyond his power, which he still maintains at 100%.
At a time when his main competitor, Carlos Alcaraz, surprised by ending his seven-year relationship with Juan Carlos Ferrero, the Italian is betting on the continuity of a master like Cahill in shaping number ones. From the early stages of Lleyton Hewitt to the final years of Andre Agassi and the prime time of Simona Halep.

Darren Cahill will continue to be Jannik Sinner's coach, at least throughout 2026
Therefore, and to avoid any speculation or controversy, Sinner has already made it clear, before the start of his Australian Open defense, that Cahill will remain throughout 2026: "Darren and I had a pleasant chat at the end of the year and we decided to continue together for at least one more season," said the Italian during the draw ceremony of the Australian major.
It is important to note that the role of Simone Vagnozzi in this team is equally, if not more, significant than that of Cahill. In principle, the Italian, responsible for the tactical and technical aspects of the San Candido player, will continue when the Australian departs.
Although the world number two prefers not to think about it yet and focuses on praising the good connection between them: "Darren and Simone make a great team, we always strive to improve," states Sinner, who will start his Australian Open defense against Hugo Gaston.
The partnership between Sinner and Cahill is not only crucial for the Italian's performance on the court but also for the strong bond between them, which also impacts the rest of the team: "Darren gives me a lot of peace of mind, I feel very secure with him in my corner, and not just me, but the whole team as well," states Jannik Sinner, who believes in the continuity of a Darren Cahill who has changed his mindset and turned him into the best player in the world, with the permission of Carlos Alcaraz.
