Mudryk has not played a game or trained with his Chelsea teammates since then. Maresca has had limited contact with the winger.

Before Chelsea's second match in the Club World Cup against Flamengo, Maresca said he last spoke to Mudryk in Poland when they played the Conference League final. Maresca explained that he was not aware of the doping news until it was communicated to him recently.

Maresca added that he does not have more information about the situation because the club has not received any further updates.

Chelsea has not officially responded to the doping charges, but the club has previously stated their support for Mudryk.
