Conte insisted after the match that leaving out Luiz was purely a "tactical decision", but reports suggest the two men clashed in the wake of Chelsea's humiliating 3-0 away defeat against Roma in the Champions League.
The Brazil global was left out of the Blues squad for Sunday's 1-0 win over Manchester United and even trained alone that morning after an apparent falling out with Conte.
"Christensen played an awesome game". It's normal. I repeat: I have to put my face in every situation, and then to sometimes make important decisions. To add to it, Nemanja Matic was sold to Manchester United against his wish and all this has lead to the rumours of Conte being unhappy with the Blues. "The coach has to make the best decision for the team, and tonight it was to play for Christensen and have (Ethan) Ampadu on the bench, good players for the present and future".
Luiz was guilty of some shocking defending against AS Roma in the Champions League.
"If I see that you are not in good form, it's normal".
He's now out of the picture, but Luiz regularly stepped in to defend his close friend and acted as a peacemaker, which the centre-back thinks Conte is now punishing him for.
"I decided this way tonight, maybe I can decide a different way in the future or I can continue the same way". I must take the best decision for the club, not for a single player. "But I do the best things for my team".
"I'd be happy to eat humble pie if I'm wrong - and there's part of me that will be pleased if I am because I've a lot of respect for the guy".
"I think that I have a squad. I try to do this".
The pair had a heated exchange last Thursday after Luiz questioned Conte's tactics and was consequently sidelined from Friday's session. But are you talking about the future? "From now until the end, every day my future is discussed".
