On a scale of one to 10 — one being everybody cheating and 10 being spotless in terms of doping — Michael Phelps predicted the Tokyo Olympics would be a “four or five.”
It wasn’t clear if Phelps was being asked about swimming specifically or all sports.
Phelps, four years into retirement, repeated comments he made at a 2017 congressional hearing examining the international anti-doping system.
“I can honestly say throughout my whole entire career, I don’t know if I ever competed in a clean field. If that’s the case, then, yeah, I don’t think anything’s changed,” he said in a CNN video interview published Friday.
