We're dealing with the vacuum that was inevitably going to be left when Wenger was gone. Once we get through that, and the club structure matures to some degree, then we can start climbing again.
Happy to swim against the tide here: I don't think it's as much of a mess as we all seem to think. I think that where we are now, is probably where we should have expected to be.
I think the main issue is our fans. We need to have patience now. We saw Liverpool go into this sort of slump and eventually sort it out, and we see ManU still struggling since Ferguson left. We are in this place now, and the main vitriol from the fans is just us getting to grips with it, and lowering our expectations until we get back on the horse. Lets not forget that some Liverpool fans were making noises about Klopp 1-2 seasons in, imagine if they had got rid at that point. We can't get toxic if Arteta takes that sort of time to start to make real progress, but I fear we will.
For me the playing squad has obvious holes but is not that bad, the ingredients are there. Although I am worried about the attitude/mentality side of things.
The club structure is new and there have been (major) teething issues with key figures departing soon after it was put in place, but I don't have major worries there, I expect that to settle down.
And when it comes to identity I think a managerial appointment like Arteta is one that will help us in a big way. This is an area we have suffered in under Emery. An identity is not a Manager. An identity is a club and their values, the Manager has to come in and adhere to those. Arteta is someone who is good for that, he understands it. Solsjkaer got his fans onside initially because he understood ManU's identity, and he is trying his darndest to ensure that it is permeating through the club at every level. Hopefully Arteta is a better tactical Manager than Solsjkaer, but I do hope he brings similar messages around our club identity.
