Where can we find another Pogba? Someone with his supreme technique with either foot, along with his height & physicality? It's impossible.
There is no one else, and that's ok. The transfers and formation from 2019 onwards have been building a team that has no place for him. Bruno is so far advanced, he's much more of a forward than a midfielder. Which means he needs two full-time defensive players behin him. Which makes Pogba out of place.
The replacement for him needs to be someone alongside Fred who can intercept, tackle, and pass forward. No need for Pogba's skill or pass variety, which is almost impossible to find anyway.
I'm convinced that the team which uses him correctly (8 or 10 in a 4-3-3 or left or CAM in a diamond) will have a monster midfielder, but aside from his first season, Ole's caretaker spell, and some bits of the end of last season, that's not happened.
