West Brom earned a hard-fought point against Chelsea at Stamford Bridge last time out, and boss Tony Pulis is unlikely to tinker with things too much for the trip to St Marys.
Here is how they could lineup..
Ben Foster has returned to full fitness, but Myhill's good performances in goal should keep him out for the foreseeable future
Injury to Johnny Evans means Gareth McAuley should switch to the left flank and James Chester will be drafted into the centre to replace him. Craig Dawson will continue in the right back berth that he has made his own this season.
Captain Jonas Olsson has probably been one of WBA's more consistent performers.
Claudio Yacob will drop deeper into defensive midfield and scan that back four, making crunching tackles to break up play and put the team back on the attack. James McClean scored against Chelsea and will be looking to notch again here.
Brunt is crucial for WBA in terms of crossing and delivery, while the experience of Morrison and Fletcher is invaluable in midfield.
Salomon Rondon continues to keep out Berahino as the first choice striker in Pulis' side. The future of Berahino will carry on being speculated for the time being, but he doesn't look like ever usurping Rondon this season.
Former Zenit star Rondon has bagged only three goals for the club this season.
