Depends for how long. We have (mistakenly in my view) put all our eggs in Arteta's basket - particularly with what now seems to be a disastrous decision to make him manager, rather than spreading the risk of his inexperience by having a director of football above him. Common sense for me says that this needs to be addressed. but as I said in the OP the real question is what the benefit of replacing him now will be when we are arguably at our lowest point and the likelihood is that anyone coming in won't have the credentials to do anything but at best improve our finishing position this season by a few places. If rebuilding this basket case will take time, then the next managerial decision should surely be with a view to the longer term - and the decision itself should not be rushed.
