Ugarte will definitely win more ball but it sounds from what Ten Hag is saying that United fans shouldn't expect to see him immediately.
Tactics are still the problem. If you press high with your forward line but then have a defensive line that sits deep then the space in the middle of the park is too great to contain any half-decent team that breaks that initial press. You don't have to believe me, just listen to Slot's post-match conference. He says exactly the same and it's what sides have been doing to United for the last 12 months.
Regardless of who you put in the midfield, with those tactics it means they need to play out of their skin every match, win the vast majority of their duels/tackles and not slip up in possession. If they don't, well you've seen what happens...
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.
