The board should back Arteta completely and give him a fair warchest, I know people will blame me in telling this. I still have faith in the process. but we need a complete overhaul upfront and in midfield and clear the deadwood because we have a lot. People expect we can finish 4th with this squad but our squad is top 7 at best. I think we should also give Martinelli a fair chance upfront next season because Auba and Laca will both be in their 30s.
We should move :
Willian
Chambers
Kolasinac
El Neny
Nketiah
Lacazette
Luiz
And we should try to get at least some players like below
Hakimi
A stand in left back
keep Guendouzi because he is better then El Neny.
try to keep Ødegaard if another CAM if anybody have other options. ESR can cover a lot of positions.
Next year we should try to have the below first eleven if we can get our targets.
Leno
Hakimi
Saliba
Gabriel
Tierney
Partey
Xhaka ( or maybe an upgrade dont know who tbf maybe Bissouma from Brighton?)
Ødegaard
Saka
Martinelli
Pepe/Auba
We definitely need better players, no doubt, but there is just too much evidence now that Arteta (and Edu) is too much of a rookie at this stage to have the chance to mold the squad. This is the most important window in the recent history of the squad, we can't botch it.
Arteta/Edu's handling of:
Saliba/Guendouzi situations
Cedric/Mari signings
Use of AMN/Willock
Willian
Inconsistent formations
Villareal debacle
is enough evidence now that they shouldn't be in the positions they are in.
Re the league position, I actually agree with you about the state of the squad. I think 7th is par for this lot on, with MC, MU, Chelsea, Liverpool, Sp**s, Leicester all have better players/squads on paper. But we will likely finish 9th/10th, with the lack of goals and home form abysmal. It can't be justified.
