Was losing Dein the problem?

They're pretty much best friends, I'm sure they discuss goings on at the club but there's nothing Dein can do in the way of getting his influence across. The mechanics of the club are different now at the top.

So Wenger wants to make more signings/retain players but the board's the problem despite what they keep telling us? Or Dein can't influence Wenger into thinking we should be acting differently in the transfer market? Or Dein's feeding Arsene bad advice/doesn't see a problem?
