Arsenal manager Arsene Wenger could make changes following Sunday’s 1-1 draw with Crystal Palace.
Per Mertesacker, Aaron Ramsey, Theo Walcott and Olivier Giroud are all pushing for recalls, but Jack Wilshere is not yet ready to play.
West Brom have reported no fresh injuries since their defeat by Watford.
Saido Berahino is expected to keep his place despite missing two penalties against the Hornets, Alex Pritchard is a doubt, while James Morrison is out.
WHAT THE MANAGERS SAY
Arsenal manager Arsene Wenger: “The season is far from over. It depends on who you play and the commitment you face.
“Against West Ham and Crystal Palace we were not efficient enough. That is a regret. It’s my job to get the team 100% ready.
“Every time it doesn’t work you question yourself, it is part of the job. In the end it is always down to me and I stand up to that.”
West Brom head coach Tony Pulis: “We get to go to these football grounds and play against great players, great football teams, at great stadiums. You relish it, you shouldn’t be nervous or worried about it.
“We’ve got the points to keep us in the Premier League, so we should really look forward to these games.”
West Brom were unfortunate to lose at home to Watford at the weekend – but when they are on the road they struggle to cause much of a goal threat.
