Its not a question of not trying, its a question of not doing a 180 and trying to go in a totally different direction overnight.
Of course, I would love United to be a dominant team. However, you have to be realistic. If your central midfield is a bunch of guys who are (mostly) coming to the end or are not natural athletes you have to accomodate. Make a long-term plan that anyone you buy in the future will be young, energic and powerful and gradually phase out the guys who cannot perform as you'd like.
Ole, Ten Hag, and Amorim have all made the mistake of trying to run before they can walk. Ole seemed to decide that just cos we got a bunch of attackers in he could just give up what had worked before. Despite him chasing Rice because he knew he didn't have the right level of dynamism in the middle of the park. Why? Likewise, Ten Hag completely dropped what had saved him and won him a League Cup, seemingly, because he signed Mason Mount. As if he'd mistaken him for a latter day Michael Essien.
We have to let time and better recruitment do their job before trying to switch it up. However, it feels like our coaches are under some diktat that they must 'play on the front foot' even its obvious we lack the personnel for it. Its weird.
