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...
