Jannik Sinner has split from coach Darren Cahill after a five-year partnership that yielded five Grand Slam titles and 95 weeks as the world No 1. Cahill worked alongside Italian Simone Vagnozzi during his tenure, and Magnus Norman is now set to replace the veteran Australian starting December 1.
The Partnership and Next Chapter
Cahill had originally planned to retire at the end of the previous season. However, the pair made a wager that if Sinner claimed the Wimbledon title, the player would control the 61-year-old’s future, leading Cahill to stay on for an additional year.
Sinner, who has been out of action due to a knee injury after securing his second consecutive Wimbledon crown in July, expressed deep gratitude for his former coach. According to Sinner, Cahill played an incredibly vital role in his journey, thanking him for his belief, honesty, and dedication while noting that his guidance will remain throughout his career.
Incoming coach Magnus Norman, a former world No 2, brings a strong track record of success. The 50-year-old Swede previously guided compatriot Robin Soderling into the top five rankings and two French Open finals, before helping Swiss player Stan Wawrinka secure three Grand Slam titles. Norman will join Simone Vagnozzi, who began working with Sinner in 2022 alongside Cahill.
Meanwhile, Alexander Zverev is guaranteed to finish 2026 as the year-end world No 1, as Sinner has chosen not to compete in any remaining ATP tournaments for the year.
Reaction to the Coaching Change
Tim Henman, speaking on Sky Sports Tennis, highlighted the magnitude of the transition. He noted that players spend immense amounts of time with their teams, and Cahill served as the lead coach after previously working with several exceptional players.
“The impact that he’s had has been on the court because of the titles that he’s won, but also the way that he’s evolved and grown as a person is very important in that journey, so it’s big shoes to fill,” Henman stated.
