Luiz is a Brazil global that has won The Champions League, FA Cup, Europa League and Premier League in two separate spells with the Premier League champions.
The Brazilian was omitted from the squad last time out when Chelsea saw off Manchester United prior to the worldwide break, however, Conte has confirmed he will be recalled for the clash with the Baggies.
While Conte confirmed Michy Batshuayi will miss the match with an ankle injury, he would not be drawn into specifics surrounding the decision to drop David Luiz. When it's a technical decision every player has to react well and accept my decision.
Speaking to Marca earlier this month, Morata said that "now there have been three games where I have not been at my best physically but I have continued to play. This is most important".
West Ham captain Noble: Intensity has jumped since Moyes appointment
I will tell them what I want on the field, but within that they have to take responsibility. "They are all well-paid". The clips I have seen at times, he has not looked a team player. "I watched him a lot at Stoke".
"Moses is progressing well - I hope to see him back next week", Conte said at a press briefing yesterday. I repeat: I don't like to speak about a single player. He helped me a lot last season, and also this season.
"This season I have another opportunity because Christensen is showing he's an important player for us".
"For Ruben, it's flawless for him to play this season - important for his development - and then to come back and play for Chelsea with great maturity".
And having plucked one regular starter from Chelsea's ranks over the summer, Mourinho may feel tempted to further weaken his rival by taking advantage of what seems like a sticky situation not too dissimilar from what happened with Diego Costa, who will officially sign for Atletico Madrid in January.
