If the whole back room staff don't get punted along with Sheerin, would Grainger be an option for a few games?
I know they are all as culpable as the manager but Sheerin really comes across as, it's my ball type situation and as has been said on here multiple times the he's stubborn so might not actually be listening to anyone.
I could be wrong but a few times on the side lines they do seem to distance themselves from each other.
