Yes I think so, I think waiting will just make the situation worse like it was with Manchester Uniter under Moyes. His chance to start showing improvement was weeks ago, but we're getting worse and worse for each passing game. I really, really doubt he can turn this ship around. And if he has indeed lost the lockeroom already (record?), then it's definitely no point.
His tactics right now are so bad that they seem almost intentionally set up to make us play like crap, the system is just plain destructive. As ZenI says, it's almost at the point where I think we would play way better if the players just started to disregard his orders and improvised everything instead...
