United caused the problem themselves, because they so much believed in Ten Hag and gave him millions of dollars to sign average players. This was how they put themselves into this financial mess. They spent hugely and nothing to show for it. Rather, they're running at loss because no club will buy those players from United on the same price, but far lower because the players don't worth the high value.
The truth is I don't know how the MU allowed itself to be fooled by ETH at that time, however as I said before, for me he was the destroyer of the MU, and he caused so much damage that the team still hasn't been able to lift its head up, it's difficult to lift a team when it's like this, however for me Amorim has done what he could, what I didn't like was his treatment of Garnacho, it's not the way he did it, but those are very internal problems.
I do not deny that ETH has made a very serious damage in the Manchester United team but the management of Man United is also wrong for what they did because they are the ones who recruited Ten Hag and they are also the ones who fully support Ten Hag with the amount of money spent, so ETH is not entirely wrong here, the management of Manchester United must also be responsible.
