How close Boris Becker came to coaching Jannik Sinner in 2022
In an interview with Corriere della Sera, Becker revealed that he almost became Sinner’s coach before Simone Vagnozzi and Darren Cahill jumped aboard.
He said: “I have never talked about it, but it’s true. I was close to becoming Jannik’s coach in 2022. Why did it not happen? Two months later, I was expecting the London trial. I explained to Jannik that I did not know how it would end, so I could not commit.
“I did not want to leave him without anything, and I provided a couple of names. One was Darren Cahill, and it was the best pick in my opinion. I believe they will work beyond 2025. I was convinced Jannik could become the world’s best player.”
Sinner has won four Grand Slams under Vagnozzi and Cahill, both of whom are expected to stay for the 2026 season.
