Well yea, you sort of answered your own questions.
A large part of his imbalance is due to not having players on the same wavelength as him around him. He’s the only player we have that is world class, everyone else is levels below. It’s hard to be consistent when you’re asked to do everything. Play advanced, create, but then also track all the way back when the team loses the ball.
It’s not about a midfielder to compliment Pogba, it’s having a quality team that can match his level. Great players play on great teams and he is not on one atm. There’s a reason why he looks out of place on United but never when he goes for international duty or his days in Juventus. He doesn’t have to do everything there and can actually rely on teammates who are capable footballers.
