With Jose Mourinho set to seal a return to the Blues' hotseat following his departure from Real Madrid, Luiz is excited about working with the Portuguese.
"If he comes back for Chelsea, I think he is a great coach," he enthused. "He has a lot of credibility in the world because he always did a great job. So of course everyone wants to have an opportunity to work with him."
Asked if he had spoken to longer-serving team-mates about what Mourinho's return would mean, the Brazilian replied: "They don't need to talk to me. I know about football.

Luiz impressed Chelsea supporters in 2012-13 with his increasingly frequent contributions in a midfield role rather than centre-back and he is enthusiastic about his development, though he has no particular preference over where he plays.
"It was amazing for me because I learned many things, new things, that can help me for the future to improve my game and to be a better player," he remarked of his new position. "That is why I work hard every day, to improve, to help the team. It was a great season for me and for the team.
"I love football. It doesn't matter if I need to play in midfield or centre-back or striker or whatever; I want to help my team. I'm happy with the ball, I'm happy because I have the best job in the world."
