Jannik Sinner Reportedly Chooses High-Profile Coach To Replace Darren Cahill

Jannik Sinner seems to have picked his next coach after reports emerged that he chose a former French Open champion who used to coach Rafael Nadal.

The world No. 1 has been coached by Darren Cahill and Simone Vagnozzi since 2022. They have helped Sinner take the necessary steps to become the top-ranked player in the world and the dominant player on hard courts since the start of 2024.

Cahill and Vagnozzi also had to help Sinner through the extreme anxiety caused by his testing positive for the banned substance clostebol at the 2024 Indian Wells Open after accidental contamination from his physiotherapist at the time, Giacomo Naldi.

Sinner has spoken openly about how much those men supported him through such a challenging time. The Italian's technical improvements and the emotional support he received mean Cahill's looming departure at the end of 2025 is a significant moment.

The Australian plans to retire from coaching and spend more time with his family. Sinner's next coach has a very hard act to follow, but the caliber of the name being reported will lead to much excitement in the tennis world.

Bolshe reported that Carlos Moya will begin working as Sinner's coach for the 2026 season. Moya, the 1998 French Open champion, transferred into coaching after his successful playing career.

In December 2016, Rafael Nadal added Moya to his team to work alongside his uncle and long-term coach, Toni Nadal. Two months later, Toni stepped away, and Moya became the tennis legend's primary coach.

Nadal won eight Grand Slam titles with Moya by his side. That included incredible triumphs after he had been injured for lengthy periods, most notably the 2022 Australian Open, when the Spaniard recovered from two sets down in the final against Daniil Medvedev.

Moya's credentials cannot be argued against. He undoubtedly learned a lot and grew as a coach after working with Nadal, and he could offer Sinner invaluable new insights about his game and how to prepare off the court.

Bolshe's reports did not confirm whether Moya will work alongside Vagnozzi. Although it is impossible to know for sure at this point, it seems more likely than not because of how much Sinner respects him.

Vagnozzi did not announce his departure with Cahill. That situation could change, but for now, it can be assumed that Vagnozzi wants to keep working alongside the two-time Australian Open champion in 2026.

Moya winning the French Open as a player and coaching the greatest clay-court player ever for several years means he could be invaluable for improving Sinner's skills on the dirt in 2026 and beyond.

Sinner showed he is formidable on any surface by reaching the 2025 Italian Open final last week, losing to Carlos Alcaraz. However, clay has been his weakest surface, and some insights from a figure like Moya could prove pivotal to him effectively challenging Alcaraz.

In other coaching news, Novak Djokovic revealed his coach for the 2025 Geneva Open and the 2025 French Open. The Serbian split from Andy Murray last week, despite initially planning to work together until the end of the clay-court swing.
