Napoli coach Rafa Benitez always expected to be replaced at Chelsea by Jose Mourinho.
Benitez and Mourinho have always disliked each other and the former Liverpool chief also revealed months ago the Special One was returning.
He said: "In football you know a lot of things you cannot say. But that Mourinho was going to come to Chelsea was clear to me. It was clear to you and to the players themselves."
