Actually Arteta doesn't have to win the big league before he can be praised, he has done so much for the club, do you think Arsenal would have been this way if not for the coach?, actually I also wish Arteta to have won a big trophy but I cannot say Arsenal made a mistake of hiring him because if Arteta leave Arsenal that means they will not be top four or even top five in premier League, the moment they just announced his leaving a lot of clubs will be willing to pay big amount for him including Manchester United they can even remove their coach now to hire Arteta, Arsenal and Aston Villa are the only two English clubs left on the champions League and Arsenal are the one I no will definitely qualify today because they are 7 to 1 in advantage.
Mate you are just over hyping this Arteta, he has done anything different from others guy, Arteta has spent over 650m Euro the highest on player transfer since he was appointed in 2019, yet he has not won any trophy in 5years in charge. That is a poor management going to champions league every season is not an achievement for club that has spent such huge sum on players.
Arteta is just overrated, he hasn't done anything in reality. Even Ten Hag was better than him, in just 2 years he spent in Manchester united, he won two trophies while Arteta is yet to have any. coaches performances are measure with the number of trophy you have for the club. Manchester united can not hire an average coach like Arteta never, Manchester united is too big for him to handle.
