Jannik Sinner has ended his five-year coaching partnership with Darren Cahill and confirmed that former world No. 2 Magnus Norman will join his team for the upcoming season, as.com reported. The 25-year-old Italian tennis star announced the major technical shift in a video statement released on November 6, 2026, closing a chapter that yielded five Grand Slam titles and the No. 1 ranking.
Sinner, who has spent the latter half of the 2026 season sidelined due to a knee injury, reflected on his journey with Cahill in a personal social media post. The collaboration began in June 2022 when Sinner was ranked among the younger talents on the circuit. Under Cahill’s guidance alongside Simone Vagnozzi, Sinner accumulated 25 of his 30 professional titles, including five Grand Slam crowns comprising two Australian Open titles, two Wimbledon titles, and one US Open victory.
“When we started working together in 2022 I was a very thin Italian boy,” Sinner said in his farewell message, noting that Cahill quickly became a trusted mentor and friend. “Melbourne, the first Grand Slams, No. 1, Wimbledon… we’ve been through a lot together. You told me you would stop after 2025, and somehow I couldn’t let go of you.”
Thank you, Darren. 🧡 pic.twitter.com/xfHHTTqPt1
Cahill had previously indicated plans to step back following the 2025 campaign, though the formal split and transition were confirmed on November 6, 2026. During their tenure together, Sinner achieved a career milestone by capturing the Internazionali BNL d’Italia in Rome, making him only the second man in tennis history to complete a career Golden Masters.
Magnus Norman Steps Into the Team
Magnus Norman will formally join Sinner’s coaching staff in December to prepare for the new season. The Swedish coach previously guided Stanislas Wawrinka to three Grand Slam titles and has also worked with compatriots Thomas Johansson and Robin Soderling.
“I feel privileged to be able to continue the work that Cahill has done with Sinner and I can’t wait to be part of the team,” Norman stated following the announcement. Norman expressed admiration for Sinner’s work ethic, pointing to the player’s humility and hunger for improvement despite already reaching the pinnacle of the sport.
Sinner’s departure from competition began in July 2026 due to his knee injury, causing him to finish his season early and relinquish the top spot in the PIF ATP Rankings to sit at No. 2. Despite missing the concluding months of the calendar, the Italian player retains a resume featuring 95 cumulative weeks as the world No. 1 since first capturing the top spot in June 2024.
Reflecting on Five Historic Seasons
The parting brings to a close one of the most productive player-coach pairings in modern men’s tennis. Sinner emphasized that the human bonds forged during grueling practice sessions and long flights outweigh the hardware collected.
“The trophies won’t be what I remember most, but everything around them,” Sinner said. “The long hours on the training court, flights, dinners and laughs. Even on the toughest days, you’ve been there.”
Cahill also offered parting thoughts on the five-year run, praising Sinner’s character and competitive integrity. “Working with Jannik has been a great honor and a privilege,” Cahill noted. “He is an incredible guy and a humble champion of whom we are all enormously proud.”
With Norman taking over the coaching reins for the upcoming campaign, the technical team aims to build upon the foundation established by Cahill and Vagnozzi, who remains part of the setup alongside other staff members.
