Ben Foster is still ruled out of action for the Baggies with a knee injury, so Boaz Myhill should continue in goal.
Gareth McAuley is a doubt after suffering from a thigh problem, but he is expected to make the starting lineup.
There should also be a start for Berahino, with Lambert joining him in the attack after scoring twice on his debut in a 4-0 win over Bristol Rovers.
Meanwhile, Delph is ruled out for City with the hamstring injury that he suffered on his debut in a defeat against Real Madrid, while Gael Clichy is sidelined with an ankle problem.
Sergio Aguero, David Silva and Samir Nasri have been suffering with a sickness bug, but they have all recovered and are expected to be in the matchday squad.
West Brom possible starting lineup:
Myhill, Lescott, McAuley, Chester, Dawson, Brunt, Morrison, Fletcher, Gardner, Lambert, Berahino
Manchester City possible starting lineup:
Hart, Sagna, Kompany, Mangala, Kolarov, Toure, Fernandinho, Silva, Navas, Sterling, Aguero
