Jannik Sinner Emotional Tribute: Will Coach Darren Cahill Retire After Vienna Open 2025 Final?

Jannik Sinner has sent an emotional message to his longtime coach Darren Cahill ahead of the Vienna Open 2025 final. The World No. 2, preparing to face Alexander Zverev, opened up about Cahill’s future and their bond as the veteran coach plans to step back from full-time coaching after nearly three years together.

The heartfelt comments came as Sinner reflected on Cahill’s role in shaping his career since 2022. With his mentor possibly retiring after this season, the Italian star finds himself balancing focus on another title run with the emotions of an impending farewell.

Jannik Sinner’s Heartfelt Message to Darren Cahill

Speaking in Vienna, Sinner paid tribute to Cahill’s influence both on and off the court. “Darren has given me a lot and I’m grateful for him. He’s not just a coach to me, much more,” Sinner said. He acknowledged Cahill’s age and decision to slow down, adding that he and co-coach Simone Vagnozzi will decide together how to move forward.

Darren Cahill, 60, has coached some of tennis’s biggest legends — Andre Agassi, Simona Halep, and Lleyton Hewitt among them. Since joining Team Sinner in mid-2022, he has played a major role in the Italian’s rise, guiding him to four Grand Slam titles and a consistent top-tier presence on the ATP Tour.

Earlier this year, Cahill confirmed that 2025 would be his last full season on tour, citing the toll of travel and decades of commitment. However, reports from Italian outlet *Il Corriere della Sera* suggest Cahill could remain with Team Sinner in a part-time advisory capacity in 2026, attending select major tournaments while letting Vagnozzi lead the main team.

Sinner Reflects on Growth, Gratitude, and Balance

Jannik Sinner has repeatedly credited Cahill and Vagnozzi for not just improving his tennis, but also his mindset. “The last weeks were a great confidence boost,” Sinner said recently. “For me, the mental aspect is in the right way, in the right spot. I feel good at the moment.”

The 2025 season has been one of Sinner’s best, with titles at the Australian Open and Wimbledon. His calm composure and improved decision-making on court have mirrored Cahill’s influence. Sinner has emphasized that beyond tactics, Cahill’s mentorship and emotional steadiness have been vital to his maturity as both an athlete and individual.

As Sinner eyes his fourth title of the year in Vienna, he is also thinking ahead. He revealed plans to skip the Paris Masters and the Davis Cup Finals in November to focus on recovery and preparation for 2026. “Even one extra week of focused work can change the start of a season,” Sinner said, underscoring his desire to manage his health and future under careful guidance.

What Lies Ahead for Team Sinner

While Cahill’s potential departure marks the end of an era, Sinner is hopeful for continued collaboration. “We said we are going to finish the year, and then we might ask him for a long chat, trying to convince him,” Sinner admitted with a smile. The Italian hinted at optimism, noting that his team aims for “something very positive” in discussions about Cahill’s role next season.

For now, Sinner’s focus remains on Vienna — a tournament he last won in 2021 — where he could once again face Zverev in a rematch of their Australian Open final. The 24-year-old Italian hopes to close an extraordinary year on a high note, proving that success is about more than trophies — it’s about loyalty, gratitude, and knowing when to pause before the next leap.

As Jannik Sinner continues his rise, his emotional tribute to Darren Cahill reflects a rare blend of respect and resolve — a champion acknowledging the mentor who helped him get there.
