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."
It is the second time this season Liverpool have been forced to act against the Russian club after Brewster's team-mate Bobby Adekanye was racially abused by fans during the game in Moscow in September.
Spartak were found guilty on that occasion and ordered to partially close their academy ground for one match.
In a statement, Kick It Out said: "Should the Spartak Moscow player be found guilty, the club must receive a far stronger punishment if Europe's governing body is truly serious about ensuring that football is an '#EqualGame'.
"It is also extremely concerning to this organisation that yet another incident of racism has taken place involving a Russian club, particularly ahead of the 2018 World Cup."
