Spartak Moscow player Leonid Mironov has been charged with racially abusing Liverpool striker Rhian Brewster, UEFA has announced.
European football's governing body took action following an incident during Wednesday's UEFA Youth League clash between the sides at Prenton Park.
A statement said: "Disciplinary proceedings have been opened following the UEFA Youth League group stage match between Liverpool FC Youth and FC Spartak Moskva Youth (2-0), played on December 6 in England.
"Charges against FC Spartak Moskva: Racist behaviour -- player Leonid Mironov -- Article 14 of the Disciplinary Regulations."
Liverpool reported Spartak to the governing body after Brewster, a member of England under-17s' World Cup-winning team, made an allegation.
The 17-year-old had to be restrained by teammates and coaching staff on the final whistle as he vented his anger.
Liveerpool later confirmed that they had "followed the proper procedure by reporting the alleged incident to UEFA."
It is the second time this season that they have made a complaint against Spartak after Brewster's teammate Bobby Adekanye was racially abused by fans during a game in Moscow in September.
On that occasion, Spartak were ordered by UEFA to partially close their academy ground for their next home fixture.
