"I was very clear in communicating": Jannik Sinner's ex-fitness coach highlights negligence of ex-physio that led to two positive dope tests
ATP
The ex-fitness coach of the reigning world number one, Jannik Sinner, Umberto Ferrara, has revealed that he informed physiotherapist Giacomo Naldi about the drawbacks of using Trofodermin, which led to Italy’s Jannik Sinner testing positive in dope tests.
The 23-year-old, who is regarded as one of the best players
currently playing in men’s tennis in the singles category, tested positive for
banned substance clostebol in two doping tests in March last year. The
reigning world number one, however, managed to escape any ban as The
International Tennis Integrity Agency (ITIA) declared him innocent following a
detailed hearing where his counsel claimed that the substance was available in
the player’s sample because he came in close contact with his physio Naldi who
used to spray for the treatment of a cut on his finger.

The World Anti-Doping Agency (WADA) appealed against the
ITIA’s verdict in the Court of Arbitration for Sport (CAS) and demanded a
two-year ban for the three-time Grand Slam winner. However, the issue finally
came to a conclusion as WADA announced that they had reached an agreement with
Sinner, which will result in the player remaining out of action for three
months.
Sinner Ferrara's former fitness coach recently spoke to Italian publication LaGazetto dello Sport, where he stated that he recommended the spray to Naldi for the treatment of a cut on his finger but informed him that he should not come in contact with Sinner. He stated that Naldi did not deny that he was not informed but stated that he did not remember.

"I have been using it [Trofodermin] for years as
prescribed by the specialist doctor as a support drug for a chronic disease,”
he said. “I was perfectly aware of the ban and I have always kept it with the
utmost caution, in my personal bathroom. I didn't give anything to [Giacomo]
Naldi (the physio), I suggested using it because he had a cut on a finger that
didn't heal and made his job complicated. I was very clear in communicating to
Naldi the nature of the product and that there was no need to get it in touch
with Jannik. In fact, I only allowed it to be used inside my personal bathroom.
Naldi did not deny that he had been informed, but said he did not remember.”

- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.

mandoist06-11-2026 - Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.
mandoist05-11-2026 - Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.
