PARIS.- The world tennis number 1, Jannik SinnerHe will work again with Umberto Ferrara, the physical trainer whom he had fired in mid -2024 after the revelation of the positive controls of the Italian player for an anabolic.
“Jannik Sinner hired Umberto Ferrara as an immediate physical trainer,” he wrote in an Avima press release, the company that represents the recent Wimbledon champion.
Since the revelation in the middle of last year of Sinner’s positives to clostebol, the world number 1 has not stopped proclaiming his innocence, claiming that he had been contaminated by a massage made by a member of his team.
The case generated a stir in tennis and stirred the circuit almost a year, with some players denouncing that the positive were announced late (made in March 2024 and without being public until August of that year) and the lightness of the sanctions.
The accidental origin of the contamination was admitted by the anti -doping authorities and the World Anti -Doping Agency (AMA) punished Sinner with a suspension agreed with him and reduced to three months, which was fulfilled between February and May 2025, for his responsibility for the acts of his collaborators.
Sinner fired Umberto Ferrara and his physiotherapist Giacomo Naldi when positive controls were made public.
In November 2024, during the ATP Masters At the end of the season, Sinner described as “excellent preparer” Ferrara.
Thinking about the US
According to the sports newspaper La Gazzetta dello Sport, Ferrara recognized in April that he used “for years” a spray that contained clostebol and that in his day he was prescribed “a specialized doctor to treat a chronic pathology.”
“I did not give it to Naldi, I suggested to use it to cure a cut that did not heal and that complicated his work. I was very clear when talking about the nature of that product and that in no case should I have come into contact with Jannik. I authorized only its use in my personal bathroom,” Ferrara said about this case.
The decision to hire the physical trainer again was taken “full agreement with the Jannik management team and within the framework of the preparation (…) for the masters 1000 of Cincinnati and the US Open,” said Avima.
“Umberto has had an important role in the development of Jannik,” said the company.
In recent months, Sinner worked with Marco Panichi, former physical trainer of Novak Djokovic, and with the physiotherapist Ulises Badio.
Just before Wimbledon, the Italian tennis player announced the end of his collaboration with both.
