During the Under-19 fixture between Liverpool and Spartak Moscow in the Uefa Youth League on Tuesday, promising winger Bobby Adekanye was targeted by some Spartak Moscow fans.
After the match, Liverpool officially complained to Uefa about alleged racist abuse against the player.
The alleged abuse at the Spartak Academy occurred when the 18-year-old came on as a 58th minute substitute.
And according to the Mirror Online, it then allegedly happened again later when he retrieved the ball after it had gone out of play.
Liverpool have complained to the governing body that there were audible racially motivated noises and gestures directed at the 18-year-old player as he made his way on to the pitch, and during the remaining 30 minutes of the match.
Academy director, Alex Inglethorpe, attended the game and reported the incident to the Uefa official on duty.
Liverpool’s youngsters suffered a 2-1 defeat in the Russian capital, with manager Steven Gerrard left “disappointed” in his side’s failure to build on their 4-0 victory over Sevilla last time out.
Steven Gerrard’s side got the match off to the perfect start on an artificial pitch in Moscow with Adam Lewis’ stunning strike putting them in front.
But Aleksandr Rudenko’s deflected free-kick soon levelled proceedings and the Russia youth international secured victory with a cool finishes in the second half.
Uefa told “BBC Sport News” it is awaiting additional reports.
Spartak also face three charges for incidents involving fans during the 1-1 draw in their Champions League game against Liverpool later that day.
Earlier in the match day Spartak advised fans not to take fireworks with them to the stadium after the club was fined 60,000€ for the fireworks and ballistics thrown at the Maribor earlier this month. They have also been banned from selling tickets to their fans for the match in Sevilla on 1 November.
Massimo Carrera, coach of Spartak, said the team and its fans were still one family, despite the problems of the past period, and the three Russian clubs seek success on the pitch, but they attach greater importance to the behavior of the fans, in the case of increased censorship of the behavior of the Russian fans, less than nine months ago at the World Cup.
Adekanye, 16 at, arrived as Liverpool and signed in the 2015 summer transfer window having found himself as the subject of a dispute between his former employers Barcelona and FIFA. He was deemed to have been signed illegally from Ajax by the Catalan giants in 2011 and, following a loan spell at PSV Eindhoven during the 2014/15 campaign, decided not to sign a new deal and subsequently moved to Merseyside as a free agent.
