Jannik Sinner has spoken candidly about his relationship with longtime coach Darren Cahill, revealing the emotional and professional bond that has shaped his rise in the ATP rankings. Cahill, who recently turned 60, has been instrumental in Sinner’s development, both on and off the court.
“Convincing Darren to stay might be my biggest challenge yet. He just turned 60, and I can understand if he wants to slow down — but I still see myself doing another year with him,” Sinner said in a recent interview.
A father figure in the team
More than just a tactical guide, Cahill has become a central figure in Sinner’s support system. “He’s more than a coach to me; he’s like a father figure who holds the team together, especially when things aren’t going perfectly,” Sinner explained. The Italian star credited Cahill for helping him navigate the pressures of entering the Top 10 and for believing in his potential early on.
Trust, growth, and continuity
Sinner also highlighted Cahill’s influence on his teammate Simone Vagnozzi, noting how the Australian coach’s presence has elevated the entire team. “He’s been fundamental to my growth and to Simone’s as well — he trusted me when I had just entered the Top 10, under a lot of pressure,”
he said.Looking ahead
As the season winds down, Sinner remains hopeful that Cahill will continue with the team. “Hopefully, we can convince him to stay at least one more season,”
he added, expressing both gratitude and optimism.The partnership between Sinner and Cahill has become one of the most respected in men’s tennis, blending experience, mentorship, and a shared vision for excellence. Whether Cahill stays on or not, his impact on Sinner’s career is already deeply felt.
