Good points NQ.
Re my apparent contradiction, I would emphasise that I'm not suggesting for a moment we should not have title winning aspirations, and I am as frustrated as anyone that the winners' mentality has been leached out of our DNA over the past decade and a half

- albeit that it could be argued there were logical reasons for this (stadium project that in hindsight did not get us where we wanted to be; the oligarchs; the tsunami of TV money).
But I feel strongly that we need to be pragmatic and realistic about how we are going to achieve what we fans crave. And I think that starts with recognising where we are. That is not defeatist. It is common sense. We need to stop the rot immediately in my view. There is no oven ready world beating manager in the market mid season, and as you rightly point out, even a Klopp or a Guardiola would struggle to fight the number of fires that need putting out at our club as things now stand.
I don't think it is far-fetched that a manager with a past connection with the Club, and who has been part of the most successful EPL team of recent times would both restore the connection with the fans that is so badly needed, and bring a winning philosophy to our team. From what I hear, Arteta is a pretty uncompromising character who would take underperforming players in hand. There is nothing to suggest that he would be the coward that we have seen Emery to be.
As I said, the next task for the manager would be to restore some feel good energy to an underperforming team. The fact that this has so palpably disappeared under Emery is in my view down to him, not a club hierarchy who did their bit over the Summer to make some exciting player signings.
Should a manager be appointed with the aim of securing top 4? No. The aim should be to win, of course, and the appointment of a so-called Europa League specialist was in hindsight too low an aspiration. What was not wrong in principle, however, was to aim to build steadily rather than expect instant success - which is, as you have said, something that was beyond even Guardiola and Klopp when they came. Given where we are
now there are worse ideas, in my view, in seeing whether we can go the Lampard route rather than appoint a more illustrious manage who is probably not available anyway.
As for the fans. I agree with you. I am not impressed by some of our fans' behaviour, and I would dearly like to see an approach by Gooners that has the best interests of the club at heart rather than knee jerking along with everyone else. What I cannot blame the fans for however is our recognition that the manager's current sitiation is untenable, and that the job is beyond him.
