Jannik Sinner has confirmed that Magnus Norman, the former world No. 2 from Sweden, will join his technical staff from the start of next month, working alongside Simone Vagnozzi. The announcement, reported by Sky Sport, makes official a handover that had been set in motion in Monte-Carlo in recent days and closes the Italian's five-year professional partnership with Darren Cahill.
The news was released through a statement in which Sinner also paid tribute to the Australian coach, and it was followed by a farewell video posted on the player's Instagram account.
Why it matters
Cahill's departure marks the end of one of the most productive coaching relationships in recent men's tennis. According to Sinner's own statement, the pair won five Grand Slam titles together and reached world No. 1 — achievements he said he had dreamed of as a boy. Replacing a figure who shaped both his game and, by Sinner's account, his character is a significant moment for a player still in the early part of his career.
Norman's arrival is, in the assessment of former ATP player Stefano Pescosolido speaking on Sky Sport Insider, a logical and conservative choice — a coach whose experience at the top of the game fits the structure Sinner has built rather than overturning it.
What Norman brings
Norman, born in 1976, was himself an elite player. Sky Sport notes that his playing career ended at just 27, after victories in Rome and in the Davis Cup and a run to the Roland Garros final. He then moved into coaching and is best known for a long collaboration with Stan Wawrinka, who retired this year; that partnership produced three Grand Slam titles.
In his first public comments, posted via his academy's Instagram profile, Norman said he holds great respect for the work Cahill and the rest of Sinner's team have done over the years and described himself as privileged to build on it. He said Sinner is already one of the best players in the world, but that what excites him most is the player's personality and mentality — young, humble and eager to keep learning despite what he has already achieved. Norman added that he looks forward to joining the team and contributing to Sinner's continued development.
Cahill's farewell and Sinner's tribute
Cahill said in the same announcement that coaching Sinner had been an honour and a particular privilege, describing him as an extraordinary young man and a humble, dedicated champion. He said trust, honesty and conviction only work when they are mutual, and that this had always been one of Sinner's strengths as an athlete — and the reason coaching him was so memorable. Cahill thanked Sinner, the team and the fans for welcoming "this Australian" into the Italian family, and wished the team continued success.
Sinner's own statement thanked Cahill for the belief he showed in him, his honesty and his commitment, saying the coach had helped him develop as both a player and a person and that the lessons would stay with him throughout his career. He said the two had shared many special moments over five years and that, while the technical collaboration was ending, their friendship would continue.
In the Instagram video, Sinner said he would miss looking up after an important point and seeing Cahill in his box. He acknowledged the season had not ended as they wanted but said that did not change what they had achieved or what those years meant to him. He thanked Cahill's family for sharing him, saying he did not take the sacrifice for granted, and added that much of who he is as a player and a person he owes to the coach.
Sinner also recalled that Cahill had told him he would stop after 2025, and joked that he somehow could not shake him. He said what he would remember most was not the trophies but everything around them — long hours on the practice court, flights, dinners, laughter and the days when everything felt heavy. He said he always knew he was in good hands and that together they were more than a team. He credited Cahill with teaching him that tennis matters but is not everything, that being a good player starts with being a good person, and that complicated things can be simple — and hoped he had taught the coach something in return, perhaps about hitting a golf ball.
Reflecting on their beginnings in 2022, Sinner described himself as an Italian kid full of questions, and said Cahill never handed him all the answers but helped him find them. He said the coach came in as one of his trainers and quickly became someone he could believe in and trust, and a friend.
Sinner's post was captioned simply "Thank you, Darren," with the video carrying the fuller message.
Norman is due to begin working with Sinner and Vagnozzi at the start of December.
