I always viewed arsenal in my time as a team who plays entertaining football and dominate the other teams. I have not seen that Arsenal under arteta. Scoring 3 goals here and there doesn't change that. Point is you lot look dull and combined with poor results one has to question the manager.That's not true, the football has been a lot better since Xmas. We've scored 3 at Leicester, 3 vs Chelsea, 4 vs West Brom, 3 vs Newcastle, 3 vs Southampton, 3 vs West Ham, 4 vs Leeds, 3 vs Benfica, & 3 vs Olympiakos. The problem is there's games still in between like vs Villa, vs Palace & last night where we do struggle. We are still inconsistent, that's the frustration.
He's doing the dirty work at least, & clearing a lot of the bloat. That's part of the reason Arsenal fans are giving him time, because even if with some squad changes in the summer, if the results don't improve next season, the squad should look in a better state for any new manager coming in. A squad with young guys like Saliba, Tierney, Gabriel, Smith-Rowe, Saka, Martinelli with some senior guys like Partey & Auba, not to mention if they bring in a couple in the summer, most managers would be happy with that as a basis to build from than guys like Mustafi, Kolasinac & Sokratis.
Again I understand Arsenal fans will back him and defend him but as a rival fan I think he is doing a poor job. Also, you talk about culture change , that is also debatable. Giving luiz, holding, even auba an extension and signing Willian and not playing Martinelli and many other questionable decisions makes one wonder is he even handling the squad well.
