The last time they "appointed" a successful manager was 1986 when Bacon Face took over they haven't appointed a good one since, 2013-present so it's fair to say they don't have the smarts to get it right :)
They are in a very very bad place from top to bottom at that shithole, Theur fans are that gullible that they think a new manager will solve everything when it's clearly not the case. To be successful the club has to be in good hands with the right people to take the club forward and they are planets away from being that club.
