Yeah - I can relate to that. It's kind of against my better judgement to write Arteta off already - given the deeper issues at our club, and the fact that once you appoint an inexperienced manager you have to allow him to make mistakes. But the reason why I think I have now done so is the non-tactical decisions that he has made (not that he is looking like a tactical genius either). Good judgment; clarity of purpose and good man management are all attributes that even an inexperienced manager should be able to display, but as far as we can tell, Arteta has shown none of this and I cannot see how this is going to improve.
So yes, I think we need a new manager. But I think also that we need to trust Arteta not to get us relegated (and possibly make a pragmatic January signing to help this), and keep him to the end of the season on the basis that proper plans are made in the mentime to get the appointment that we need, because this experiment is not working.
