Sinner confirms split from coach Darren Cahill after five trophy-laden years

Jannik Sinner has confirmed that his coaching partnership with Darren Cahill has come to an end, posting a heartfelt message on social media after the pair's five-year alliance drew to a close, Sky Sports Tennis reported.

The split follows months of speculation over the Australian's future, with Cahill long rumoured to be stepping back from tennis coaching, according to Tennis365. Sinner has now put the uncertainty to rest with statements from both player and coach.

The announcement lands just as Sinner's new arrangement for next season takes shape. Yahoo Sports reported that the world number one has already recruited Magnus Norman as his coach for the 2027 season, a move widely seen as a coup given Norman's own standing in the sport.

Cahill first began working with Sinner in 2022, and alongside Simone Vagnozzi the trio built one of the most successful alliances in the modern game, guiding the Italian to five Grand Slam titles and the world number one ranking.

In comments released by Sinner, he said: "Darren has been an incredibly important part of my journey. Together with Simone and the whole team, we have achieved things I dreamed of growing up."

He added: "Winning five Grand Slam titles and reaching world No. 1 together are achievements I will always treasure, but what means just as much is the relationship we have built along the way."

Sinner also thanked Cahill directly, saying: "I want to thank Darren for his belief in me, his honesty and his dedication. He has helped me grow both as a player and as a person, and his guidance will stay with me throughout my career."

In a separate, more personal message posted to Instagram and reported by Tennis365, Sinner reflected on the years spent together away from the trophies. He wrote: "You came in as one of my coaches and quickly became much more: someone I could believe in, someone I could trust. A friend."

He continued: "I always knew I was in good hands. With you, we were more than a team," before adding: "I'll miss looking up after a big point and seeing you in my box. This season didn't end the way we wanted, but that doesn't change what we did."

Cahill, who has previously coached Andre Agassi and Simona Halep, returned the sentiment in his own statement, describing the role as a special honour. He said: "He's an amazing young man and a humble, dedicated champion that we are all incredibly proud of."

The timing of the farewell coincides with Norman's confirmed appointment, closing one chapter of Sinner's career just as the next begins to take shape heading into the 2027 season.

Attention now turns to how Sinner integrates Norman into his set-up alongside Vagnozzi, with the coaching reshuffle set to define the build-up to his campaign next year.
