Sources close to Sina told BBC Sport that he felt Ferrara, who worked with Matteo Berrettini, learned from his mistakes.
Ferrara holds a Pharmaceutical Technology degree and was specially selected by Sinner to advise on anti-doping issues.
The initial independent court found that Ferrara offered Naldi a warning – but it was knowledgeable that it contained prohibited substances and that physiology would treat sinners with naked hands.
As part of his defense – the court decision was outlined in August last year, Sina’s legal team believed that “it was not Mr. Ferrara’s wrong gravity, not the player responsible, but rather his choice to appoint Mr. Ferrara first, while his oversight”.
Vadar said that in reconciliation with sinners, the sinner tested positive due to “negligence of his entourage,” which, according to its regulations, was the negligence of the athletes to take responsibility.
The BBC Sport asked Sinner’s representative if Ferrara would be held accountable for anti-doping matters again.
But the sinner believes he can trust Ferrara again, and for players pursuing the biggest prize, reintroducing a familiar face is crucial to maintaining himself at the top of the game.
