This Neymar vs Alvaro incident (VIDEO BELOW) was an altercation between the two that later ended up in a full fledged brawl between Paris SG and Marseille’s players towards the end of their Le Classique game. The referee was forced to give out FIVE red cards, and the likes of Layvin Kurzawa, Leandro Paredes and Jordan Amavi were all sent off. Neymar later alleged that Alvaro was racist towards him (see him speaking to the fourth official at the end of the video). VAR was used for the Neymar dismissal.
