Jannik Sinner’s coaching team have created a monster.
Over years of meticulous alteration and hard work, the Italian has gone from a promising youngster into undeniably one of the top two players in the world.
Were it not for Carlos Alcaraz, it really feels like there is nobody on the ATP Tour who could even come close to him.
He may share a friendly relationship with the Spaniard, but there’s no denying that Jannik Sinner will wish he were alone at the top. After all, he made the final of all four Grand Slams with ease and was only stopped in Paris and New York by his great rival.
How many Grand Slam titles will Jannik Sinner win in 2026?
The Italian’s coaching team will hope to take what has been an overwhelmingly positive 2025 and translate it into even more success next year.
Jannik Sinner’s coach reviews their 2025 season
Taking to Instagram to rate the last 11 months, it was Simone Vagnozzi who was keen to outline just how much hard work went into the continued triumphs they earned throughout the year.
The Italian thanked his fellow coaches, but most of all their player, who is the perfect, hard-working and malleable individual on whom their impressions are made.

Vagnozzi wrote: “Best epilogue of an incredible season.
“A year full of successes, but also complicated, with difficult moments … where the difference is made by those small, sometimes unnoticeable details. The truth is, in the most difficult moments, this team sticks even more together. Everyone tries to put a part of themselves in order to come out even stronger, driven by that obsession with IMPOSSIBLE perfection.
“Bravo Jannik, who is the first to never want to be satisfied, but to want to improve. Great athlete and great man.
“Thank you Jannik and thank you whole team.”
Why Jannik Sinner is not playing the Davis Cup this year
Despite an incredible campaign, Sinner opted against playing for Italy at the Davis Cup this year whilst his nation bid for a third-straight victory.
If they were to accomplish this feat, they’d be the first nation in 53 years to manage it.
And yet, the 24-year-old was unmoved, having explained the reasons behind his absence at length.
Sinner admitted: “It wasn’t an easy decision, but after Turin, the goal is to start off on the right foot in Australia.
“It doesn’t seem like it, but a week of preparation in that period can make a difference. We already won the Davis Cup in 2023 and 2024 and this time we decided like this with my team.”
Boris Becker asked tennis fans to give Sinner space after this decision, given that the four-time Grand Slam champion received some backlash from Italian media.
However, with the tennis schedule seemingly only increasing in volume, he cannot be blamed for finding time to rest wherever possible.
