Also find that interesting.
The way I see it, if you want to play with a high line, you'd want a back line that are good one versus one. I mean, that's bound to happen when you have most of the possession and play higher up the pitch. I would rate wan-Bissaka and Shaw as being good one v one (although both has been out of form lately), but they're often higher up when we get countered on. The same goes for playing out from the back. Maguire and Lindelöf, at times, have a good pass in them, but they're not particularly comfortable on the ball when being pressed. And they're not mobile enough to create space for others. Matic and Pogba seems comfortable on the ball, but both are to slow and take to many touches. Look at the difference when Carrick or Scholes used to receive the ball and get pressed. They both knew where the press was coming from and they already knew what to do with the ball. After they'd passed the ball on, they would moved into a new position, ready to receive the ball again.
