Besides La Liga will file a complaint
The president of the Spanish Sports Council (CSD), Miguel Cardenal, talked about the offensive banners seen this Wednesday in Cornellà-El Prat against FC Barcelona. "The banners and the chants of this Wednesday are unacceptable and will be studied by the Anti-violence comission," he said.
Meanwhile, the Spanish La Liga (LFP) announced they will file a complaint against these acts, despite they did not organize the match, as it was a Copa del Rey game —organized by the Spanish Federation of Football. Remember that the referee didn't talk about the chants and banners on his report.
