Also against the fans of the Portuguese club a complaint was filed with the UEFA disciplinary committee. They blocked the stadium stairs.
Ajax fans came to fist with the police in Estádio da Luz before the Champions League match. This happened when the agents wanted the first rows of user sections to be free. The police took over and removed the supporters from the Amsterdam club from the first rows. Fans of Ajax have broken their chairs and threw them at the agents.
