Unlikely he will leave them for any club outside of the Championship IMO so thats us, you and Coventry set to be upset......are you looking for a new manager then? Wilder on a tightrope?
Wilder's contract is up at the end of the season. If he fails to deliver the playoffs at least then it probably won't be renewed. We're currently 9 points off the bottom playoff place, with 12 games left.
Coyle wouldn't take a job outside the Championship I expect, though you are in a decent position to get there soon.
