Danny Drinkwater has regained fitness following a knock, but he can only make the bench as Conte names the same XI that defeated United at Stamford Bridge a fortnight ago.
As for the Baggies, whose manager Tony Pulis is under pressure, two changes have been made to the team that were beaten 1-0 by Huddersfield Town as Salomon Rondon and Matt Phillips come into the side.
West Bromwich Albion: Foster; McAuley, Hegazi, Evans; Phillips, Krychowiak, Barry, Livermore, Gibbs; Rondon, Rodriguez
Subs: Myhill, Nyom, Robson-Kanu, Yacob, Brunt, McClean, Burke
Chelsea: Courtois; Azpilicueta, Christensen, Cahill; Zappacosta, Bakayoko, Kante, Fabregas, Alonso; Hazard, Morata
Subs: Caballero, Rudger, Luiz, Drinkwater, Ampadu, Pedro, Willian
