Cahill to leave Sinner's coaching team at year's end

Darren Cahill, the Australian coach instrumental in Jannik Sinner's rise to dominance, will depart from the Italian's team at the conclusion of 2024. According to BBC Sport, Cahill joined Sinner's coaching setup in June 2022 when the then-25-year-old ranked outside the world's top 10 and had never reached a Grand Slam quarter-final.

Over the past two and a half years, Cahill has worked alongside Italian coach Simone Vagnozzi to transform Sinner into one of tennis's dominant forces. The partnership has yielded five Grand Slam titles and 95 weeks at world number one, a remarkable trajectory that began from a position of relative obscurity on the professional circuit.

Sinner's recent Wimbledon victory in July 2026, where he successfully defended his title against Alexander Zverev in a four-set final, marked another milestone in their collaboration. However, an injury sustained after that triumph has sidelined the 25-year-old since the grass-court championship. The absence allowed Zverev to reclaim the world number one ranking, ending Sinner's extended spell at the top.

Sinner is scheduled to make his competitive return at the Six Kings Slam tournament in Saudi Arabia next month, marking his first appearance since Wimbledon. His comeback will occur without Cahill's presence on the coaching staff, as the Australian's departure represents a significant transition for the player.

Swedish coach Magnus Norman, who spent years working with recently retired Stan Wawrinka, will assume a role in Sinner's coaching team for the upcoming season. Norman's appointment signals continuity in the player's support structure despite Cahill's exit.

Sinner expressed his gratitude for Cahill's contributions to his development.

Darren has been an incredibly important part of my journey. Together with Simone and the whole team, we have achieved things I dreamed of growing up. He has helped me grow both as a player and as a person, and his guidance will stay with me throughout my career.

Cahill reflected on his time with the world number one contender, stating:

Working with Jannik has been a special honour and privilege.
