Absolutely, maybe not Overmars for me personally. We do indeed need a DoF that actually knows how to do the job and is able to tell the manager "no, that player does not fit our strategy" though. Ten Hag shouldn't be expected to be anything other than a coach and a manager.
The fact that we were actively looking at him to be our manager for months and it seems like nothing was done to identify players that fit his strategy is shocking. And during the preseason, when ETH has to focus on training his new players, he's expected to tell our DoF who to buy? This summer has shown the total lack of preparation from the club.
