Liverpool have vowed to make a formal complaint to Fifa after young striker Rhian Brewster allegedly received racial abuse from a Spartak Moscow player.
The incident is alleged to have occurred during the Uefa Youth League match between the two clubs at Tranmere's Prenton Park stadium today.
The Liverpool Echo reports that Brewster "had to be dragged away by Reds team-mates and staff" at the final whistle after Liverpool completed their 2-0 victory.
Brewster informed referee Mohammed Al-Hakim of the alleged abuse and this information has already been passed on to the fourth official.
Steven Gerrard, the former Liverpool midfielder who now coaches the club's youth team, said: "It's difficult for me to comment on it right now. It's something that the club will look into and deal with.
"I'd rather talk about Rhian Brewster's performance. I don't want to take any gloss off that because he was superb. The only thing that was missing from his performance was a goal. He held the ball up so well and put in a shift for us."
Brewster starred for England Under-17s last month as they won the World Cup in their age group, scoring in the final as his team won 5-2. He is regarded as one of Liverpool's brightest young talents and even appeared for the first team on their pre-season tour.
Liverpool's youth match with Spartak comes ahead of tonight's full Champions League match at Anfield, with Liverpool needing just a point to qualify for the next stage.
