Chelsea goalkeeper Thibaut Courtois admits growing up idolising Real Madrid captain Iker Casillas.

Courtois will be between the posts for Atletico Madrid in the derby against Real.

"He was my idol as a child. I like him a lot and have a lot of respect for him, but he is an opponent and I will always want to beat him.

"I admire his speed between the posts. He has very good reflexes. He is a very good goalkeeper, in general," said Courtois.
