About a year after having separated from Umberto Ferrara, the physical trainer who was involved in his clostebol doping case, Jannik Sinner has decided to recust the development with him.
This is a decision that could make great noise in the coming days or even in the coming weeks. Indeed, about a year after having separated from Umberto Ferrara, Jannik Sinner has just announced that he was going to work again with his former physical trainer, which he describes as “an excellent trainer”.
Involved in the clostebol doping case, an anabolic steroid, which had led to the three -month suspension of the current world number 1 (between February and May 2025), Ferrara will therefore be part of the staff of the recent Wimbledon winner. “Jannik Sinner hired Umberto Ferrara as a physical trainer with immediate effect. This decision was made in consultation with the management team of Jannik, as part of the preparation of the next tournaments, notably Cincinnati and the US Open “, can notably read in the press release from Avima, the management company which represents the Italian player.
Ferrara: “I was very clear on the nature of the product”
“Umberto has already played an important role in Jannik’s sporting development, and its return testifies to a renewed desire to focus on consistency and performance at the highest level,” said the press release. Last April, Ferrara returned to this doping affair linked to a spray containing clostebol that Giacomo Naldi, the former physiotherapist from Sinner, had used to treat a cut.
“I did not give him anything, I suggested to him to use it because he had a finger that did not heal and which made him the task difficult. I was very clear on the nature of the product and on the need to never put it in contact with Jannik. In fact, I only allowed its use in my personal bathroom. Naldi did not deny that he had been informed, but said he did not remember it, “said the former former physical trainer of the world number 1, during an interview with the Gazzetta Dello Sport.
