There were details to clarify in the case of positive doping results of Jannik Sinner, with the detailed version unknown by either of the two individuals who have been considered responsible for his contamination by clostebol. One of them, Umberto Ferrara, who has returned to the circuit working alongside Berrettini, has explained in great detail what happened.

Their professional image has been damaged; they were immediately dismissed from Jannik Sinner's work team, and the general consensus is that they were responsible for the two positive doping results that have led to the Italian being banned from competing for three months. Umberto Ferrara and Luca Naldi are the main suspects, and now, in an interview by the former for the Gazzetta dello Sport, the physical trainer directly points to the physiotherapist as the one responsible for what happened.

"I have suffered severe damage to my personal and professional reputation," he begins by saying before explaining why he had that medication, strictly forbidden by the World Anti-Doping Agency. "I have been using the spray Trofodermin for years as part of the treatment for a chronic illness I suffer from. It is prescribed by doctors, I knew it was banned for athletes, and I always carried it in my personal toiletry bag with all sorts of precautions," he comments.

One of the big questions is why Luca Naldi used that spray for having a cut on his hand. "I simply suggested he use it because the wound he had on his finger was not healing and was hindering his work. I clearly explained the implications it had and that he could not come into contact with Jannik; in fact, I made him apply it in my bathroom," he explains, noting that the physiotherapist did not deny this but claimed not to remember.

"Considering all the warnings I gave him, I could not imagine he had treated Sinner without gloves. As soon as we found out that clostebol was the banned substance, I realized where it came from, and we were quickly able to explain everything that happened. In fact, I provided evidence of purchasing the spray myself at a pharmacy in Bologna. I have been hurt by how superficially this issue has been handled, even with ill intent, and what is clear to me is that I would not trust the behavior of others," says a visibly resentful Ferrara towards Naldi.

Asked about how Jannik Sinner has handled this whole process, the physical trainer now working with Berrettini has a clear view. "He has shown extraordinary maturity, backed by the conviction that his arguments were completely true. His work ethic and dedication are very special, which constantly drives his improvement. I was very saddened by the way our professional relationship ended; it has been a pleasure working with him," states a Umberto Ferrara hurt by what he perceived as an attack on his honor but pleased with the support from the tennis world, from coaches to players.
