Sinner's head coach explains why they have decided to play the Mutua Madrid Open 2026, what Carlos Alcaraz represents for him from San Cándido, and what their relationship is like.

Jannik Sinner went through critical moments during his match at the 2026 Australian Open against Spizzirri. With a score of 2-1 and serving in the third set, he went to his corner where his team was, visibly concerned about the cramps that were preventing him from moving. Simone Vagnozzi advised him to control his breathing and try to relax, while Darren Cahill appeared like lightning, telling the Italian to endure and reassuring him that they would take the blame if he had to leave the court but to tough it out through that third set.

Perhaps many still do not remember, but Darren Cahill, coach of Jannik Sinner, confessed during a chat with ESPN in the middle of the 2025 Australian Open that he had talked to his player about Joao Fonseca. The Australian coach explained that he had asked Sinner how he saw the Brazilian, and Sinner replied that he thought Fonseca would finish in the top 25 by the end of the season. More than nine months after those words, Joao is ranked 28th in the world and still has a chance in Paris to continue improving. Sinner's words back then were considered excessive and almost utopian by many so-called tennis experts.

The world number 1 shows his most human and emotional side in a documentary recorded during his three-month suspension for doping.
A couple of days after the tough final of the 2025 ATP Cincinnati, in a match where Jannik Sinner couldn't give more and ended up retiring with a 0-5 disadvantage, Darren Cahill came out to clarify certain doubts about the world number one: "Sinner caught a small virus on Sunday that worsened the following day. We hope to have him back on the courts tomorrow," said the coach about the Italian in preparation for the 2025 US Open.
On SportsCenter, Darren Cahill says that Sinner caught “a bit of a virus” on Sunday that only got worse the next day.
