Athletic Bilbao striker Nico Williams faced racist chants from Atletico Madrid fans during the confrontation between the two teams at the Civitas Metropolitano stadium, in the 33rd round of the Spanish League. According to the BBC, Williams was harassed by Rojiblancos fans after he equalized for his Basque team. Nico Williams - Iñaki's younger brother - tried to convince referee Juan Martinez to stop play after the officials were alerted to the alleged chants. At the same time, Antoine Griezmann and Jose Maria Jimenez urged their team's fans to stop chanting before play resumed. This is not the first time that Atletico fans have behaved in this way, as Real Madrid previously filed a complaint with the Spanish legal authorities last month, after a video clip on social media showed Atletico fans chanting racist language against Brazilian striker Vinicius Junior. It is worth noting that Atletico Madrid defeated Bilbao in this confrontation with a score of 3-1.
