Darren Cahill to leave Jannik Sinner's team as Magnus Norman joins for 2027

Darren Cahill will leave Jannik Sinner's coaching team at the end of 2026, with Magnus Norman joining the Italian's camp for next season, BBC Sport reported. The departure brings to a close a partnership in which Sinner won five Grand Slam titles and spent 95 weeks at the top of the world rankings.

Watch the highlights:

Cahill, the 61-year-old Australian, joined the team in June 2022. At that point, Sinner was ranked just outside the world's top 10 and had not advanced beyond a Grand Slam quarter-final. Working alongside Italian coach Simone Vagnozzi, Cahill helped oversee the period in which Sinner became a multiple major champion and reached world number one.

Sinner, now 25, credited Cahill with contributing to his development away from competition as well as to his tennis. In comments carried by BBC Sport, he said the work with Cahill, Vagnozzi and the wider team had allowed him to achieve ambitions he had held since childhood. He also indicated that Cahill's guidance would remain important to him beyond their time working together.

The coaching announcement comes during an extended absence from competition. According to the BBC report, injury has kept Sinner out since he won Wimbledon for a second consecutive year in July. Alexander Zverev recently replaced him at the top of the rankings. Sinner is scheduled to return at the Six Kings Slam in Saudi Arabia next month; the report describes that appearance as a planned comeback, not a completed return.

Norman will arrive after a long coaching association with Stan Wawrinka, who recently retired. The Swede's move into Sinner's team is set for next season, while Cahill's departure is due at the end of this year. Cahill described his work with Sinner as an honour and a privilege.

The Australian had initially intended to step away at the end of 2025. That timetable changed after he told Sinner at Wimbledon that the player could decide whether he stayed, provided he won the title. Cahill consequently remained involved beyond that original departure date, but the partnership is now set to conclude at the end of 2026.
