Sure i get what you're all saying and i know it's a bit crazy to talk about replacing Arteta, but as i said above Abramovich's Chelsea and I'd argue some continental clubs would do it if they thought it necessary so it's not beyond contemplation
It's not based on anger but it's certainly an argumemt based on personal preference, as someone who pays to go to the games it's depressing to think we're stuck with Xhaka and Zin and the no-left-back system for the forseeable future, personally i can't stand it and so purely from a selfish POV, if Arteta won't change it it's always going to annoy me and make me inclined to want to see what somone else could do with that squad (or most of it)
When Tierney goes in the summer - which he surely will - it will be a really depressing moment, especially if he then does really well for someone like Newcastle
I'll say one more time that different managers work with different teams at different points of their evolution
But sure we will of course keep Arteta and all well and good and I'll just have to suck it up
