Enzo Maresca says he believes Mykhailo Murdyk’s protestations of innocence over his positive doping test and does not think the situation will be the end of the Ukrainian’s Chelsea career. Mudryk tested positive for the banned substance meldonium after playing for Ukraine last month and is facing a lengthy ban if the Football Association go on to charge him with an anti-doping rule violation.

Chelsea and their Ukrainian winger Mykhaylo Mudryk are facing a turbulent period following allegations of a failed drug test. With the potential for a lengthy ban looming, the player's future in soccer is hanging in the balance.

Chelsea trust Mykhailo Mudryk and are fully behind him after the Ukrainian winger was contacted by the Football Association over an adverse analytical finding following a routine anti-doping test, coach Enzo Maresca said on Wednesday.
