WATCH: Kylian Mbappe reacts to controversy during Espanyol-Real Madrid

Real Madrid are still reeling from their defeat to Espanyol on Saturday night, which saw the gap at the top of La Liga close to a solitary point. Specifically, the reigning champions are enraged at the decision not to send off Carlos Romero in the second half, especially as it was he that scored the winning goal for Los Pericos.

On the hour mark at the Stage Front Stadium, Romero tried to stop Kylian Mbappe racing away with the ball, and in doing so, he caught the Real Madrid attacker very high. He was shown a yellow card by on-field referee Alejandro Muniz Ruiz, and the decision was backed by VAR official Javier Iglesias Villanueva, much to the chagrin of Los Blancos.
