Jannik Sinner is one of Italy's favorite sports figures and he does not hide his football preference. When he is not busy chasing Grand Slams, the 24-year-old World No.2 cheers for AC Milan.
The short answer
Yes. Sinner supports Milan. Plain and simple.
Why we know
He made his support public in a memorable moment at the Internazionali d'Italia in May 2022. After beating fellow Italian Fabio Fognini, who supports Inter, Sinner wrote Forza Milan on a live TV camera. That was not subtle.
More fan moments
- In November 2023 he was a special guest at San Siro for Milan's Champions League match against Borussia Dortmund. Fans in the Curva Sud greeted him with chants before kick-off.
- He is close friends with goalkeeper Gianluigi Donnarumma. Before a European final involving Donnarumma, Sinner said he did not want to put anyone in a difficult spot, adding that he is a Milan fan but would be happy to see an Italian team win.
Tennis résumé, just so you remember who we are talking about
Sinner is not just a football fan who happens to hold a racket. He has been one of the leading men in world tennis for several seasons, sharing the spotlight with Carlos Alcaraz. Key facts:
- Current ranking: World No.2.
- He held the No.1 spot for 65 weeks before being overtaken in September.
- Grand Slam haul: four titles total. That includes two Australian Opens, one Wimbledon, and one US Open.
- Notable win: he lifted the Wimbledon gentlemen's singles trophy in July 2025.
A little background
Before tennis took over, Sinner started skiing at age three. He later focused on tennis and quickly rose through the ranks to become Italy's top male player.
Where things stand with Milan
Milan were sitting second in Serie A this season. Sinner will be hoping his club returns to the Champions League stage in 2026-27, so he can watch them from the stands rather than from a TV camera.
Bottom line: if you need a one-line answer for a pub quiz, write AC Milan. Jannik Sinner is a Rossoneri fan and he has made that clear on more than one occasion.
