Maybe Erik Ten Hag's success in presenting the FA Cup title is the reason for management to retain him. I think if that is the reason, it certainly does not match the large investment value that has been disbursed. Of course, anyone would be disappointed if the performance of their favorite team does not experience significant changes. I think it is time for management to give an ultimatum to Ten Hag so that he can improve the team's performance.
He doesn't seem to be aware, there's something wrong with his training model and the management doesn't see it well. Transfer facilities have been provided but no progress looks good. If I compare him to Arteta, he should have started to show improvement. Because I used to doubt him, but ended up with better progress than Ten Hag. Maybe Arteta spent longer at Arsenal, but at that time Arteta did not have many options to buy players. If I'm not mistaken, these 3 years Arsenal are more open to buying players.
