West Brom v Blues: Lewis Cox's predicted line-up as three changes selected
Ryan Mason is forced into at least one change as Birmingham come to town on Wednesday - but he may consider more.
Jayson Molumby is suspended in midfield after his costly dismissal at Coventry on Saturday and it opens the door to either Toby Collyer or Ousmane Diakite filling the void.
Collyer is yet to kickstart his Albion career and Mason vowed he still has full confidence in the on-loan Manchester United man delivering this season.
He would be the starter most supporters would crave, with a more creative flair than the more workmanlike and defensively sound option of Diakite.
Mason may ponder switches at full-back and I have done so with my line-up below - introducing Callum Styles and Alfie Gilchrist for Charlie Taylor and George Campbell respectively.
Styles and Gilchrist are more offensive options and it suits more playing at home.
Nat Phillips and Chris Mepham have both been below-par at centre-back of late, but will probably be selected to continue, though former Blues skipper Krystian Bielik is waiting in the wings and pushing to start.
