Bielsa seems an utterly insane appointment to make in the middle of the season. Maybe in November but I can't see it working now. The one positive would be if we go down under him he likely gets us back up should he decide to stay.
I remember saying after Bournemouth if you're going to change the manager do it now and get someone like Bielsa in to give him time on the training pitch.
We haven't got the luxury of Bielsa now. It needs to be someone who can just come in and grind it out. Allardyce/Pulis/Dyche/Moyes. The squad isn't capable of anything else and why Lampard ditched his preferred way of playing.
