I don't think the midfield enforcer is a priority but for that sort of defensive option in there I'd go for McNair, who although mainly for CB could split positional duties between there and midfield
Lewis Travis is also one I'd consider, probably going to leave Blackburn and he's the sort of leader Wilder will want and the sort we'll need considering who we'll be losing. He's good in all defensive aspects, a bit of a shithouse and is a tidy if unspectacular footballer. Like McNair, can play RCB too
