The possible counter to that argument is would any manager coming in be able to pluck a tune from such a discordant bunch of players? Maybe. However, it's certainly not a given, so do you give a new manager the rest of the season to get up to speed for the next, or hope that the team suddenly finds some form?
What's beautiful is that normally when you have a dogshit hand with no chance of winning, the next move is forced upon you - you have to twist. However, in this case, to twist may also be as damaging as sticking. They really are fucked.
