Terry and Zouma at the back, Pedro makes Blues debut
Pedro makes his debut for Chelsea in the game against West Brom at The Hawthorns, where Kurt Zouma starts alongside John Terry at the back.
Following speculation over whether skipper Terry, who was taken off at Manchester City last weekend, would start, it is in fact Gary Cahill who drops to the bench.
Chelsea welcome keeper Thibaut Courtois back from suspension, while there are places on the bench for youngsters Ruben Loftus-Cheek and Bertrand Traore.
Pedro makes his first appearance in English football, having this week joined the Blues from Barcelona, while fellow new arrival Baba Rahman is not in the matchday squad, so Cesar Azpilicueta continues at left-back.
Albion, meanwhile, have new loan signing Serge Gnabry on the bench and do not include Saido Berahino, who has been linked with a move.
West Brom: Myhill, Dawson, McAuley, Olsson, Brunt, McManaman, Morrison, Fletcher, Yacob, McClean, Rondon.
Subs: Rose, Chester, Lescott, Gnabry, Gardner, Anichebe, Lambert.
Chelsea: Courtois; Ivanovic, Zouma, Terry, Azpilicueta; Matic, Fabregas; Pedro, Willian, Hazard; Diego Costa.
Subs: Begovic, Cahill, Mikel, Loftus-Cheek, Traore, Remy, Falcao.
