Liverpool manager Arne Slot says more needs to be done to avoid racism in football following allegations by Real Madrid's Brazilian forward Vinicius Jr that he was subjected to racist abuse from Benfica's Argentine winger Gianluca Prestianni, Reuters reported. 

Real's 1-0 Champions League playoff first-leg win at Benfica on Tuesday was overshadowed by Vinicius accusing Prestianni of directing a racist slur at him, a charge denied by the Portuguese club, the player and their manager Jose Mourinho.

European soccer's governing body UEFA said it was reviewing the incident, which led to the game being halted for 11 minutes under FIFA's anti-racism protocol, according to Reuters.
