I can see both sides cos they were kind of drifting when he went there and he got them challenging FAIRLY quickly, and this is probably his first REALLY disappointing season, etc etc. So I get that it'd be pretty harsh to sack the guy, but man the evidence is really piling up that he just doesn't have what it takes. He's also benefitted from a load of really good signings and guys like Saka coming through. You're right I think - a really good manager would've won trophies in those circs.
I'm not going to stick my neck out and write them off next season, but there's nowhere to hide for him now: the pressure's going to be massive.
Like, lets compare to klopp with us
First year (half a season, so like artetas FA cup season), 8th, EL final - lost, league cup - lost
2nd season, 4th in the league, nothing in the cups
3rd - 4th, CL final - lost
4th - 2nd, CL winner
5th - 1st, club world cup, super cup
6th - 3rd, nothing in the cups.
First season of regression.
7th - 2nd, FA cup & Carabao winners, CL final. So close but right back on the horse
8th - 5th, nothing in the cups.
regression
9th - 3rd, Carabao winners. Bye bye klopp.
Year on year progression, a final, or a trophy. Yes he's a well established manager and arteta is still cutting his teeth. But imagine those first 5 years and replace them with 2nds and 1 FA cup. Nah. We won't tolerate it
