Jose Mourinho burst into Real Madrid dressing room to find "the rat"

Jerzy Dudek has explained how a furious Jose Mourinho stormed into the Real Madrid dressing room to try and find out who the "mole" was. 

The goalkeeper published a book about his career and spoke about his time with Los Blancos.

Ahead of a clash with Barcelona, someone in the squad gave away a secret to the media, saying that Pepe would start the game in midfield. 

Dudek wrote: "He came into the dressing room with a face like thunder and had a go at us because the press had found out that Pepe was going to play in midfield.

"Where's the rat? Is it you, Granero?

"He insisted that there was a rat in the dressing room and said that he wouldn't stop until he found out who it was. Then he closed the door and left."
