The returning Blues boss recently called and spoke with the Brazilian who was thrilled to learn that the Portuguese tactician is a fan of his work.
"I am eager to start working with Mourinho, my phone rang recently and it was Mourinho," he told Globo Esporte.
"It surprised me. We talked a lot and he said nice things.
"That made me very happy, and I told him that he can count on me, that I'll do what I can to help him be a winner at his new spell at the club.
"I was already eager to work with him and I am now even more motivated after finding out that he wants to work with me. I am feeling we will have a great season."
