West Brom v Blues: Lewis Cox's predicted line-up as three changes selected

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.

Mason will weigh up whether the same forward four of Mikey Johnston, Isaac Price, Karlan Grant and Aune Heggebo will continue.

Heggebo will surely lead the line after his run of three goals in two games - he won praise from Mason in Tuesday's press conference - and Johnston is likely to start again following his two assists before Saturday's controversial substitution.

Samuel Iling-Junior is the option Mason has if he decides to tweak. Tammer Bany may come on to the bench with Molumby absent, but it is unrealistic to think Bany will make a first Albion start.
