Willian is backing Alexandre Pato for success with Chelsea.
Pato is yet to play for the Blues having last played a competitive match in November but he could make his debut in the FA Cup next week against Manchester City.
Willian told the Daily Express: “I think he can bring a lot of things for us. He’s quick, he has good technique, and he scores goals. He’s a very good player. He can help us a lot. I think he’s hungry to show the world what he can do. That is why he came to Chelsea.
“He wants to improve, and be a champion here. He knows that he had so much pressure on him in Brazil, but he has to stay calm and he can play better here in England, he can win titles here.”
