Darren Cahill Reveals If He’ll Coach Jannik Sinner After 2026 Season

Darren Cahill and Jannik Sinner discussed their future partnership after the end of the 2025 season. Cahill, who wanted to leave after the 2025 season, decided to coach him for this season.

Sinner is playing at the Italian Open at present and has reached the fourth round after eliminating Alexei Popyrin. Last year in Rome, the four-time Grand Slam champion lost to Carlos Alcaraz in the final. Later at the French Open, he squandered a two-set deficit and three match points before losing the final to Alcaraz.

At the Australian Open last year, Sinner revealed in a press conference that Cahill would be retiring at the end of the season. The Aussie coach recently gave an interview to La Gazzetta dello Sport, during which he revealed whether he is planning to stay in Sinner’s entourage next year as well.

We’ll see… I didn’t think I would be coaching Jannik in 2026, yet here I am. There are no bets at the moment; my goal is to do the best job possible for Sinner and the team this year. Then we will talk at the end of the season, as we did last year, and decide with the utmost serenity. What I can assure you is that Sinner will be my last player as a coach.

Under both Cahill and Simone Vagnozzi (both joined his team in 2022), Sinner won the four Majors, completed the Sunshine Double, became the World No.1 player, and also lifted two back-to-back ATP Finals.

He is also chasing history in his home tournament because winning it will not only make him the first man to lift six consecutive Masters 1000 titles, but also the second man after Novak Djokovic to complete the Career Golden Masters.

Darren Cahill says Jannik Sinner is not a robot

Although Jannik Sinner is very consistent on the tour and rarely shows emotions while playing, he is not an emotionless robot, said Darren Cahill during that aforementioned interview with La Gazzetta dello Sport. As per Cahill, his protege has a “dangerous” side that loves adrenaline.

He is not one at all. There is a part of him that loves danger, and that is not seen much on the court because when he is playing a match, he has that internal computer that works continuously, and there is a certain security in the way he plays. He calculates the probabilities of winning the point by choosing a certain shot with less risk, and that is the characteristic of a winning player.

Sinner is on a 30-match winning streak. If he wins two more matches, he will break Novak Djokovic’s 31-match winning streak in the Masters 1000s.

In life, however, it’s not exactly the same. He likes motor racing, speed. He likes adrenaline. But these two souls come together in a single player, incredibly professional: training, nutrition, rest; he tries to step onto the court each time with the goal of growing and improving.

Darren Cahill added

The last time Sinner lost a Masters 1000 match was in the third round of the 2025 Shanghai Masters, where he was forced to hand the walkover to Tallon Griekspoor due to cramps. Since then, he took home the 2025 Paris Masters, completed the Sunshine Double this year (became the eighth man to achieve this), defeated defending champion Carlos Alcaraz in the Monte-Carlo Masters final, and breezed past Alexander Zverev in the Madrid Open final.

The win over the Spaniard in The Principality helped Sinner reclaim his No.1 spot in the rankings. Because Alcaraz is not playing in Rome due to a wrist injury, it’s only helping Sinner increase the rankings gap between them.
