When Jannik Sinner stepped onto the practice courts this week, a familiar face was back by his side. Nearly a year after one of tennis’s most controversial dismissals, the Italian star has made a decision that’s sending shockwaves through the sport: bringing back fitness coach Umberto Ferrara, the man at the center of his doping case nightmare.
This isn’t just another coaching reunion. It’s a calculated gamble that could either restore the partnership that helped Sinner reach World No.1Â or reignite the controversy that nearly derailed his career. With major tournaments looming, Sinner has chosen loyalty over caution, continuity over public opinion.
How Will Ferrara’s Return Impact Sinner’s Championship Defense?
Sinner has officially reappointed Umberto Ferrara as his fitness coach with immediate effect. The announcement comes as the World No.1 prepares for upcoming tournaments, including the Cincinnati Open and US Open. A statement from Sinner’s team emphasized that, “Umberto has played an important role in Jannik’s development to date, and his return reflects a renewed focus on continuity and performance at the highest level.”
Here it is.

The reunion carries significant weight given their history together. Ferrara originally joined Sinner’s team in late May 2022 and played a crucial role in the Italian’s rise to the top of the rankings. However, their working relationship ended abruptly in August 2024 following Sinner’s positive tests for the banned substance clostebol.
The contamination was traced back to Ferrara’s medication, creating a situation that would define both their careers. Speaking about the incident, Ferrara explained: “I have been using it for years because it was prescribed by a specialist as a support drug for a chronic disease. I was perfectly aware of the ban, and I have always kept it with the utmost caution, in my personal beauty case.”
The chain of events that followed revealed how quickly careers can unravel. The spray containing clostebol was given to physiotherapist Giacomo Naldi, who then treated Sinner without wearing gloves, leading to inadvertent contamination. Ferrara maintains he warned Naldi about the risks, stating: “I didn’t give anything to Naldi, I suggested using it because he had a cut on his finger that wasn’t healing and was making his job difficult.”
A Turbulent Year for Ferrara in the Background
Following his dismissal from Sinner’s team, Ferrara’s journey through professional tennis became a test of resilience. He found work with fellow Italian player Matteo Berrettini in November 2024, a collaboration that sparked controversy given Ferrara’s involvement in the doping case.
However, Berrettini defended his decision to hire Ferrara, with Sinner even showing support from afar. The World No.1 said, “Umberto is really a great trainer, that’s all I can say. He will surely do a very good job with Matteo.” This public backing hinted at Sinner’s continued faith in his former coach, despite their professional separation.
The partnership between Ferrara and Berrettini proved short-lived, lasting only six months before ending in June 2025. The split occurred after Berrettini withdrew from the Italian Open due to another abdominal injury. According to reports, the decision was made “by mutual agreement” after Berrettini’s latest injury setback.
Meanwhile, Sinner was making his own significant changes. This separation coincided with Sinner dismissing fitness coach Marco Panichi and physiotherapist Ulises Badio before Wimbledon 2025. Panichi and Badio had joined Sinner’s team in September 2024 as replacements for Ferrara and Naldi.
Their departure came after reports suggested Panichi had disclosed sensitive information about Sinner, including details about the player’s emotional reaction after losing the French Open final.
The timing of Ferrara’s comeback appears strategic, coming on the heels of Sinner’s greatest triumph. The Italian recently won his first Wimbledon title in July 2025, defeating Carlos Alcaraz in the final to claim his fourth Grand Slam title. Sinner became the first man from his country to win Wimbledon in the tournament’s 148-year history.
Now, with Ferrara back in the fold, Sinner prepares to defend his Cincinnati Open title and then gears up for the US Open, where he is also the defending champion.
