nah he was crucified by the Arsenal ‘fans’, certainly online, they only really forgave him when Arteta arrived and his performances/confidence improved. Even now you’ll have some who are still outraged that he’d stand up for himself like that
It’s the underlying attitude that because players are paid a lot that the fans are entitled to say/shout what they like about them - there’s definitely a bit of a disconnect here in terms of the reaction to Dier and the reaction to Xhaka
