I feel at odds with the prevailing sentiment in here. The result is highly disappointing but the performance much less so. There's no powerful evidence Arteta's approach has failed. It was a match with few opportunities decided by a superb free kick. Perhaps the subs could have been better.
The difference between what we've been doing and a title-winning dynasty is in the margins. Seems to me there's a psychological aspect as well and that's where fans can play a part.
I believe Arsenal fans should gird their loins and recognise we've had a highly effective transfer window and we have an excellent squad and manager despite losing to Liverpool at Anfield.
Scapegoating the manager or particular players has reached an odious level. It's a buzzkill even if you're a fan and it likely affects the mood internally.
There's plenty of things about Arsenal that are more negative than Arteta's tactical outlook: most of the posts in this thread for starters.
Toys were chucked from the pram all summer over signings, then we got the signings we wanted so now it's the selection, the mentality, players who need to be put in the rubbish bin, etc. Gyökeres, who had the same sort of limited influence as Mo Salah and curtailed support, is now "mid-Championship level". The kind of doomed jobsworth mindset that's horrible at home and at work.
Toughen up buttercups, this is the one world we've got. If we say we're Arsenal fans then we know our positive task is to support the club's effort, not jack off to grievance porn on a daily basis.
