Varane saw action in the 5-1 triumph.
"I'm glad to play and give good performances. Sergio Ramos is a very good player and we compliment each other to perfection," said the Frenchman.
"I hope to be a centre back here for the next ten years and that what Mourinho said comes true. The manager helps me improve and he knows exactly when he must use me. We centre backs can't afford to make any mistakes. It is a difficult position, but I continue to improve with the help of my teammates."
