Atletico Madrid fans whistled Thibaut Courtois every time he touched the ball, and threw toy rats in his direction during Atleti's 3-1 home loss to Real Madrid.

Courtois, who was Atleti's keeper from 2011 to 2014, left to the club for Chelsea before moving to Real Madrid.

Courtois has called out Diego Simeone in the past, saying that Simeone only criticizes Real Madrid to gain popularity with his own supporters.
