Chelsea's decision to sign Luiz has been met with surprise and criticism from many pundits, but the Brazil international is confident he will prove his worth.
He said: "I have tried to improve and mature day by day. When you try new things of course you improve, that's why I tried a new league.
"But I want to continue to improve here. I never want to think that I know everything. I want to learn every day. I feel at home, I feel like I never left. I have a great relationship with everyone.
"The coach (Conte) loves football, that's why he's a passionate guy on the bench, celebrating and supporting the team.
"He's a specialist in tactics and training in a tactical way, I'm excited to learn under him.
Every single coach has been important in my professional life. I want to learn, especially with him and his Italian style in a tactical way, this can make the difference."
