He will place faith in the pair, who were ignored and sold respectively by Mourinho.
Conte said: “I think that Victor Moses is playing very well. Not only now, but at the start of the season. I asked my club to have a look at him, because I wanted to assess him with my own eyes. And he’s a very good guy.
“I’m pleased to have him in our squad. He’s a fantastic player and a fantastic man as well, and this is important for me.
“For David Luiz, coming back to Chelsea, this is a great challenge but he’s started very well. With great concentration and focus, with a great will to show why he’s decided to come back to wear this shirt, and to prove it was the right choice.
“In his career he’s won a lot and played with good teams. He’s very good, with a good technique. When you have David Luiz you can play from the back. My idea of football, I love this: to start to play from the back.
“For me, he’s also a good defender. We are working a lot with him but also the other defenders, to stay always focused in every single moment of the game. But I’m pleased that David Luiz came back to Chelsea.”
