I don't know what the end goal is with Arteta. Me, I want my team to improve season on season, to look at least as if they are building towards something. What that something is I don't know, because let's be honest, when you are competing with City's money & Pep, with a Klopp inspired Liverpool, & with Chelsea with Tuchel & a billion pound squad, its going to be difficult to overtake them.
You are right, perhaps unexpectedly this would be our best chance of top 4, because of the situations at Utd & Spurs. But let's be honest, in terms of quality & depth, this isn't a top 4 squad.
The attack certainly shouldn't be a top 4 attack, & that's the area of the first XI that needs most improvement. But due to shedding of a lot of players that weren't seen as the future, we also lack depth. I realise that, I can accept that, as long as we make improvements in transfer windows going forward.
However, i suspect ultimately, given the quality of the teams (& coaches) we are competing with, Arteta might not get us to where we want to be. However as we have seen with football, lots can change. Conte can quickly be out of Spurs as quick as he was installed, managers don't seem to last long at Chelsea, Pep & Klopp might be coming towards the end of their cycle. Everything might go up in the air again, & that's the great thing about football.
