This will be an Edu problem more than an Arteta one no? His job is meant to ben ensuring we follow a certain way of doing things i.e. play style and age profile so that even when Arteta leaves the club, the next manager can be profiled based on our 'vision'.
If Arteta wants washed up mercenaries Edu should be strong enough to say no. If they didnt learn from Özil and Willian with these large contracts then there is officially no hope for this club.
Surely teams these days should be building squads and bringing managers in to compliment all of that, rather than shapeshifting based on the manager's way of thinking. Managers come and go way too often these days to do that, and its why I think United struggled in the Moyes/LvG/Mourinho period.
That’s the issue, you need someone to have this vision and then hire in accordance. Hire a DoF, manager who buy young, play a certain way etc. We don’t have that, you need someone above the DoF to have that vision.
This is one of the reasons why guys like Saliba, Guendouzi, Martinelli have been cast aside for older players.
