Real Madrid and Benfica meet for the second leg on 25 February
Trent Alexander-Arnold said the alleged racist abuse of team-mate Vinicius Junior during Real Madrid's Champions League match at Benfica was a "disgrace to football", while opposition manager Jose Mourinho was criticised for his comments on the incident.
The match was halted for 10 minutes after Vinicius reported alleged racist abuse by Benfica's Gianluca Prestianni to referee Francois Letexier, and he and his team-mates temporarily left the field.
The Brazil forward, who has been the victim of numerous incidents of racist abuse during his playing career, said "Racists are, above all, cowards" in a post on his Instagram.
Benfica manager Mourinho claimed Vinicius did not "celebrate in a respectful way" after his stunning goal in the 1-0 win preceded the incident at the Estadio da Luz.
