The Chelsea forward, who cost $108 million when signed from Shakhtar Donetsk in 2023, said he had never knowingly broken any rules.

Former Russian tennis player Maria Sharapova had been the most high-profile case of an athlete being banned for using meldonium. A failed drugs test at the 2016 Australian Open led to a two-year ban issued by the International Tennis Federation, with Sharapova accepting she had made “a huge mistake” in taking the substance.

Chelsea and Mykhailo Mudryk have issued statements after the Football Association notified all parties of an adverse finding during a routine drugs test.
