Jannik Sinner coy about retirement question after Wimbledon triumph

Cahill, who mentored former world No 1s Lleyton Hewitt and Andre Agassi, has been part of Sinner's camp since July 2022, sharing all the coaching duties with Simone Vagnozzi.

Under their guidance, the Italian went from rising star of the game to one of the biggest names in tennis as he won two Australian Open titles, the 2024 US Open and most recently Wimbledon. He also became the first Italian to become No 1 in the ATP Rankings when he climbed to the top in June 2024.

But Sinner has been searching for a new coach since the start of the year as Cahill informed the 23-year-old that he would retire from coaching at the end of this season.

Following Sinner's four-set win over Carlos Alcaraz in the Wimbledon final, the Australian was asked during the post-match press conference if he would reconsider the decision to retire and replied: "I don't want to answer this (smiling).

"You know what, you just need to ask Jannik that. Ask Jannik. Are you guys going to be in the press conference with him?"

During the Italian portion of Sinner's press conference the question was put to the newly-crowned Wimbledon champion.

"It depends. Whether I want to tell the truth or not," he started off before revealing they had a bet and the ball is now firmly in his court when it comes to Cahill's future.

"We had a bet before the final. He said: 'If you win tomorrow, you can decide whether or not I stay.' Now the choice is mine. I've always looked for a person who is honest, a person who gives me a lot, not necessarily only on the tennis court, but [about] how to live."

If Cahill - who received the ATP Coach of the Year Award in 2023 alongside Vagnozzi - does indeed stay on, then he is unlikely to accompany Sinner on a full-time basis with Vagnozzi likely to fulfil that role.

The four-time Grand Slam winner added: "The season is long. There are a lot of tournaments. You never know. But let's just say I won the bet, and so we'll see what happens."
