Jannik Sinner has parted ways with his Australian coach Darren Cahill, the world No.2 said in a video posted on social media, with reports indicating former world No.2 Magnus Norman is poised to step in.
Norman arrives with experience and a proven record having taken compatriot Robin Soderling to the top five in the rankings and two French Open finals before guiding Swiss Stan Wawrinka to three grand slam titles.
The 50-year-old Swede will take his place alongside assistant coach Simone Vagnozzi, who like Cahill started working with Italian Sinner in 2022.

“A large part of who I am, as a player and as a person, I owe to you,” Sinner said on Friday about Cahill in a video posted on Instagram.
“Of these five seasons, I won’t forget a single day. Thank you, my friend, for everything. It has been a privilege.”
In a statement, Cahill called Sinner and “amazing young man and wished him continued success.
“Working with Jannik has been a special honor and privilege. He’s an amazing young man and a humble, dedicated champion that we are all incredibly proud of,” Cahill said.
“Trust, honesty and belief only work when it’s exchanged both ways, and this has been Jannik’s strength as an athlete
“It’s also the reason that makes coaching someone like him such a memorable experience.
“I want to thank Jannik, the entire team, and all the fans for welcoming this Aussie into the wonderful Italian family. I wish the team nothing but continued success for the coming years”
Sinner has been out of action with a persistent knee injury since capturing his fifth grand slam title at this year’s Wimbledon in July, but is expected to make his comeback in December at the Six Kings Slam exhibition in Saudi Arabia.
Cahill, a veteran coach who has guided four players to the world No.1 spot, expected to leave Sinner’s team in 2025 but stayed on for another year and said at Wimbledon he would stay until the end of 2026 before discussing his future.
Sinner went from a rising talent to the tennis summit under Cahill, although his ascent was interrupted by a three-month ban in 2025 after two positive tests for trace amounts of clostebol in 2024, for which he was cleared of wrongdoing.
Alexander Zverev is guaranteed to finish 2026 as the year-end No.1, with Sinner deciding not to play in any of the remaining ATP tournaments this year.
