I think you will come to learn very quickly that Ten Hag is not as open to the media like Postecoglu is. He probably comes straight into the team next weekend and plays 60-70 minutes.
On the other hand, I understand what you are saying about the tactics and the space between midfield and defense. However, the major reason for that space is because our midfield play is terrible.
Casemiro is a major culprit.
He keeps vacating his position to play high yet he doesn't have the legs to recover. So instead of building play from the back, you will often see United kick the ball into midfield and then someone will try a chipped ball behind to a striker or a winger where we will often lose possession.
We force the play too much which always leaves our defenders exposed.
