Jannik Sinner Parts Ways with Physio and Fitness Coach After Investigation

Jannik Sinner, the world number one tennis player, has ended his professional relationship with his physiotherapist Giacomo Naldi and fitness trainer Umberto Ferrara following an investigation into his positive tests for a banned substance.

Sinner twice tested positive for clostebol, a steroid known for its muscle-building properties, in March. Last week, a tribunal cleared Sinner of any fault or negligence, with the International Tennis Integrity Agency (ITIA) determining that he had been inadvertently contaminated by Naldi.

The contamination occurred when Naldi, who had been treating a cut on his own hand with an over-the-counter spray provided by Ferrara, proceeded to carry out treatments on Sinner without realizing the potential for contamination.

In a press conference at the US Open on Friday, Sinner expressed his gratitude for the contributions of Naldi and Ferrara to his career but explained his decision to part ways with them.

“They have been a huge part of my career,” Sinner stated. “We made incredible progress and achieved a lot of success with a great team behind me. But because of these mistakes, I don’t feel confident continuing with them.”

Sinner also shared that the situation had been difficult for him over the past few months. “I was struggling a lot in the last months. Now I was waiting for the result, and now I just need some clean air,” he added.
