Chelsea boss Jose Mourinho denies accusing Esteban Granero of being a "rat" when they were together at Real Madrid.

Jerzy Dudek declared in his new book that Mourinho, when he was managing Real Madrid, accused Granero of being a "rat" after a clash with Barcelona.

"Don't make me laugh. Dudek really said that? Granero is a great professional and a lifelong friend of mine," Mourinho told Marca.

"What do you say the book is about? About training goalkeepers? And what is he out to do, transmit his experience to the children that are dreaming of being goalkeepers?"
