Atletico Madrid released a statement on Tuesday condemning the racist chanting aimed at Vinicius Junior before the Madrid derby, saying they will ban club members who are identified as having been involved.
A group of Atletico fans were filmed singing "Vinicius, you're a monkey" before Sunday's derby at the Metropolitano stadium, which Real Madrid went on to win 2-1, while local media also reported that monkey noises and chants of "Vinicius, die" were heard throughout the game.
LaLiga has said it will be filing an official report on what happened with Spain's Anti-violence Commission and the Spanish football federation (RFEF)'s Disciplinary Committee.
