Real Madrid forward Kylian Mbappe said Benfica's Gianluca Prestianni should be banned from the Champions League after the Argentine was accused of directing a racist slur at Vinicius Jr during the Spanish side's 1-0 playoff first-leg win on Tuesday, Reuters reported. 

Denying the accusation, Prestianni said the Brazilian misheard him.

The incident occurred shortly after Vinicius had curled Real into the lead five minutes into the second half in Lisbon, according to Reuters.
