Anderlecht is facing a sanction from the UEFA after the misconduct of a number of supporters during the away match against Real Sociedad. The club will have to play a upcoming away match in the Conference League without fans. The sanction is a result of the incidents that took place during the match, where seats were broken and thrown into the lower tier. The UEFA had already imposed a conditional penalty on Anderlecht two years ago after incidents in the away match against West Ham United. This sanction is now being activated. Anderlecht is deeply disappointed in the behavior of the supporters and is announcing measures against the troublemakers. The club management is waiting for the sanction from the UEFA and will take measures to prevent this type of incident from happening again in the future. The supporters who do behave in a football stadium are the victims of the misconduct of a few others. Anderlecht will not only have to do without the vocal support of the fans, but also pay a financial penalty. The match against Real Sociedad was briefly interrupted due to the incidents and the local police entered the visitors' section and made eight arrests.
