Jannik Sinner parts ways with coach Darren Cahill
Tennis star Jannik Sinner has announced the end of his five-year coaching partnership with Darren Cahill. The Italian player, who rose to world number one and won five Grand Slam titles under Cahill’s guidance since 2022, shared an emotional farewell on social media, describing the Australian coach as a mentor and friend who helped him grow both as an athlete and a person.
Cahill, who had previously considered retiring at the end of 2025, will depart following the conclusion of the 2026 season. Sinner, who has been sidelined by a knee injury since winning Wimbledon in July, is expected to return to competition in December at the Six Kings Slam in Saudi Arabia.
Magnus Norman, a former world number two and successful coach of Stan Wawrinka, is set to join Sinner’s technical team in early December. Norman will work alongside existing assistant coach Simone Vagnozzi to help Sinner reclaim the top spot in the ATP rankings from Alexander Zverev.
