To the first point, what do you think? Of course no. Are we expecting to qualify for Europe? No but we have to see genuine improvement in performances and results and at least see a vision for what we're trying to achieve. But in modern football, patience doesnt exist. If a manager doesnt get the fans onside in a few months then good luck!
As for the second point, its really annoying that Arteta has become the poster boy for good young managers. It's like when Leicester won the league. Every club started thinking that anything is possible. It isnt. Arteta was an anomaly, not a blueprint. As was Leicester and look at them now.
