Jannik Sinner’s sacked trainer breaks silence on why he carried banned substance in house
Jannik Sinner’s sacked former fitness trainer has claimed he warned ex-physio Giacomo Naldi not to allow a trofodermin spray anywhere near the tennis star. Umberto Ferrara and Naldi were both axed from Sinner’s team after he was cleared of wrongdoing over twice testing positive for banned substance clostebol in March 2024.
However, the world No. 1 is now serving a three-month ban after the World Anti-doping Agency (WADA) appealed that decision to the Court of Arbitration for Sport (CAS), claiming an athlete must bear some responsibility for the negligence of their team. Sinner was found to have been contaminated after Naldi, who had used the trofodermin spray suggested to him by Ferrara on his own cut, gave the Italian a massage. A very small sample of clostebol, a steroid banned by WADA but which is an ingredient in the spray, was found in the 23-year-old’s system at Indian Wells last year.
