The tennis star has warned Jannik Sinner that his three-month doping suspension will persist over his career like a "cloud" – and raised doubts about the scheduling of the penalty last year.
Sinner completed a three-month suspension in February 2025 after the global anti-doping body approved his account that a banned anabolic steroid, the steroid clostebol, had entered his system accidentally.
"This shadow will trail him just as the cloud of Covid will follow me, for the rest of his, or my career," Djokovic stated in an interview on Piers Morgan: Uncensored.
"It's just something that, it was so significant, and after such events, over time it will fade, but I don't think it will disappear. There will inevitably exist a certain group of people that will always try to bring that forward."
Djokovic expressed belief that Sinner, his frequent training companion, "had no intentional involvement", but he then scrutinized how the player arranged to serve his time without missing a grand slam.
"There is the lack of transparency, the inconsistency, the convenience [of] the ban coming between the slams, so he doesn't miss out the others – it simply appeared highly unusual," he further commented.
"I really don't like how the case was being handled and it was evident numerous fellow athletes, both male and female, who had comparable circumstances coming out in the media and asserting it represented favorable handling."
