Spartak Moscow defender Leonid Mironov has been charged with racially abusing Liverpool striker Rhian Brewster, Uefa has announced, reports BBC Sport.
The alleged incident took place during a Uefa Youth League game at Prenton Park, which Liverpool won 2-0.
England Under-17 international Brewster had to be calmed down by team-mates and staff at the end of Wednesday's match.
The 17-year-old told the referee and the fourth official was informed, while Liverpool also complained to Uefa.
European football's governing body said the case will be dealt with by their Control, Ethics and Disciplinary Body, with a date for the hearing yet to be confirmed.
