Valencia winger Denis Cheryshev is being investigated by the World Anti-Doping Agency.

WADA announced it will open an investigation into Valencia and Russia winger Cheryshev over a charge of alleged doping.

“The case is now in the hands of the Spanish Anti-Doping Agency (AEPSAD)," WADA Media Relations and Communications Manager Maggie Durand confirmed in an interview with Sport Express.

The probe was initiated after Cheryshev's father, Dimitri, stated during an interview with Sport Weekend that the player had received growth hormone treatment before the World Cup, where Cheryshev scored four times in five matches, although the publication suggested that he may have been referring instead to growth factors, which are naturally occurring and commonly used in medicine to treat a range of health problems.
