They are probably looking to get sm sort of new manager bounce now to just about save them this season. Similar to Sunderland last season with O'neil's sacking.
He'd have been a useful appointment to keep things tight and tide them over while they waited for someone good to become available. Instead they kept him on as long as possible and let the team reach tipping point at the worst possible moment. They have such a nightmare run-in and I hope they go down. Play the worst football in the league.
