Country: England
I like the cultural changes Arteta haas made most of all. The team and wider club are so unified ATM. Arteta is responsible for this, I didnt see it emerging early on but it's clear now.
The point of change was summer 21; we have recruited brilliantly since then and got young hungry players with the right combination of technical skill and ambition who are good humans to boot. They greatly helped the club culture and bought into the project and standards required, but in addition, we can also play ball now
