Carvalho: Mourinho will make Chelsea's Luiz better defender
He told the Daily Mail: "Under Jose, David Luiz will come back a lot quicker than he does now. He is a good player and he can still go forward, but he will have to get back quicker.
"Jose let me go forward because he thought that I could do it well, but he didn't encourage me to do it because he likes defenders to defend and to start the play from behind.
"And you have to know the right moment to go forward, to read the game and feel the right time. This is what David Luiz will find."
