Jannik Sinner and Darren Cahill end partnership after 2026; Magnus Norman joins the team

The announcement

Jannik Sinner and Darren Cahill will end their technical collaboration at the close of the 2026 season, after five years of shared success. The split was confirmed on 6 November 2026 in a statement from Sinner's team, and Sinner also spoke about it in a video posted on Instagram. Magnus Norman, a Swedish coach and former world No. 2, will join Sinner's technical team from December, working alongside Simone Vagnozzi. Darren Cahill, an Australian coach, had joined the team in June 2022 and, working with Vagnozzi, played a central role in the rise of the Italian to the top of the sport. The timeline below sets out the main milestones of the partnership and the change now underway.

Five years together

During the partnership Sinner won five Grand Slam titles and two ATP Finals titles, according to the statement from his team. He also completed the Career Golden Masters by winning all nine ATP Masters 1000 events. In June 2024 he reached the top of the world rankings for the first time. The announcement presents the five years as a shared success, with Cahill's role described as fundamental to the player's growth. The results were framed as the outcome of years of dedication and continuous improvement. The bar chart compares the Grand Slam and ATP Finals titles won in the period.

Sinner on Cahill

Sinner thanked his coach in a long statement, calling him a central figure in his career.

“Darren has been an incredibly important part of my journey. Together with Simone and the whole team, we reached goals I dreamed of as a child.”

Sinner said the five Grand Slam titles and the world No. 1 ranking would stay with him, but the relationship built along the way mattered just as much. He thanked Cahill for placing his trust in him and for his honesty and dedication, adding that the coach had helped him grow both as a player and as a person. He said Cahill's teaching would accompany him throughout his career. The announcement also describes a friendship that went beyond the professional side.

Sinner ended by addressing the end of their working relationship directly.

“Even though our collaboration as coach and student is coming to an end, our friendship will continue.”

What changes next

Norman's arrival in December means the change takes effect once the 2026 season concludes. He will work alongside Simone Vagnozzi, and the rest of Sinner's staff, led by Vagnozzi, stays in place. The personal bond between the two men is expected to continue after the professional partnership ends. The split opens a new phase in Sinner's career without the coach who helped shape his rise to the top of the rankings. Cahill's partnership with Sinner, which began in June 2022, ends with the 2026 season.
