It’s not just about nullifying Devine.It doesn't nullify him.
Pretty sure @Bobbage isn't asking him to be playing as an actual winger.
More to play inside off the left, and Wiley can provide the width. So Devine can roam and pick up central spaces.
Not what I'd pick, but it's really not that big of an issue as people like to make out, as he still plays central when he's in formation sense, playing out wide.
It also brings concerns defensively with Devine who tucking in.
Wiley could be considered more of an attacking wingback and with Devine tucked in, Wiley ends up being on his own when defending with little defensive support.
The Rovers goal happened down that side. Think it even happened with Pol and Offiah when Devine was played wide - Bolton and Watford.
If Devine does stay wide left as not suggested you do nullify him.
