The one issue with this is White is also suspended, so you'd have to move Sweat back to LCB, Callens to the middle, and Brillant to RCB. I just don't want Brillant going full 90 at RCB. I don't mind it when we're chasing a goal, just not for a whole match. But if we were to go with that, then slot Lewis at LW and Wallace at LWB as you suggested.Just spitballin', but how about a flat 3-4-3?
Wallace, Villa, Harrison
Sweat, Maxi, Herrera, Allen?
Callens, Brillant, White
Could put Lewis in at LW, slide Wallace back to LWB, and Sweat to the bench.
As others have mentioned as well, I wouldn't mind seeing Harrison start on the bench for this one to give him some rest.
