With security in and around the Santiago Bernabeu tighter than ever, supporters clashed with police and one another ahead of a Champions League meeting between Real Madrid and Legia Warsaw on Tuesday.
In the wake of the 2015 terrorist attacks in Paris, officials in Spain are taking no chances during the hosting of high-profile sporting events.
Goal reporters in Madrid noted that security within the Spanish capital was more intense than that normally laid on for El Clasico fixtures between Real and Barcelona.
