UEFA is awaiting match reports amid an allegation of racist abuse against Liverpool teenager Rhian Brewster.
The Merseyside club reported Spartak Moscow to the governing body after the 17-year-old striker, who had to be restrained by team-mates and coaching staff on the final whistle in their UEFA Youth League game, made a complaint following his side's 2-0 victory.
A UEFA spokesman said: 'UEFA will be waiting to receive the official match reports. We will be able to provide you with official information on this in the next days.'
Liverpool confirmed in the wake of the incident that they had 'followed the proper procedure by reporting the alleged incident to UEFA', and it is understood the report relates to alleged racist abuse.
