Jannik Sinner and Darren Cahill to split, with Magnus Norman replacing him

Darren Cahill joined Jannik Sinner's team in June 2022, according to the BBC. The Australian coach helped guide the Italian to five Grand Slam titles and the world number one ranking.

Cahill was one of Sinner's two coaches, L'Équipe reported. His departure brings an end to a partnership that covered a major period of Sinner's success.

On November 6, 2026, Sinner announced the end of their collaboration in a video posted on social media, according to L'Équipe.

The message was also a personal tribute. Fanpage reported that Sinner credited Cahill with shaping much of who he is, both as a player and as a person, and thanked him for their time together.

The departure is scheduled for the end of 2026, rather than taking immediate effect, according to ANSA.it and the BBC.

Magnus Norman was named as the replacement, La Repubblica reported. The Swedish coach previously worked for a long period with Stan Wawrinka.

Reports differ in how they describe the partnership's length. La Repubblica calls it five years, while L'Équipe and the BBC give June 2022 as Cahill's joining date, which puts it at a little over four years.

The succession has been announced: Cahill will leave at the season's conclusion, and Norman will take his place. ANSA.it describes Norman as joining the five-time Grand Slam winner's coaching team.

Norman brings experience as both a player and a coach. According to Adnkronos, he reached world number two in 2000; La Repubblica highlights his long association with Wawrinka.

The remaining detail is the handover. The supplied coverage establishes Cahill's end-of-season departure and Norman's appointment, but does not specify Norman's exact starting date or how responsibilities within Sinner's coaching team will be divided.
