I think there is no doubt we are in a real mess as a club and it doesn't feel like we've really laid any decent foundations as yet in terms of going forwards and that will likely take some time to address. But I look at the teams who've outdone us this year, like Chelsea, United and spurs, and I don't see teams light years away from us so I don't think closing them down is that difficult in theory.
On Arteta, the jury is still very much out for me. I'm not sure I've seen signs this season to know if he's going to be the person to try to take us forward. The thing I'd say lots of the talk about him was he was well respected maybe the next big coach. At the time there seemed to be a we need to go for him because we can't spend big and being the now established managers.
Now we seem to be getting more of a well of course he needs big backing but that was originally one of the supposed reasons we weren't bringing in established managers and Emery had the same issue that is a very poor squad but that wasn't enough to excuse his underachievement.
Of course Arteta has next season but it's a very important one for him where he gets a full crack and he needs to demonstrate tangible progress in my eyes. That should include targeting champions League return which requires us not dropping so many silly points as a result of poor defensive play and presumably coaching.
