Put it this way:

You know how Fernandes plays w/o Pogba? The amount of creative load he has in those games? Well, it's ~30% of the team by himself. Sancho has the same for Dortmund when they're fully fit.

He is *definitely* their main man and it isn't close. https://twitter.com/utdrobbo/status/1391042375447990278

This is one example: a front four of Pogba, Fernandes, Sancho and Cavani is amongst the best in world football. The depth with Rashford, Greenwood, Martial (if he stays) and Van de Beek means we can rotate a lot if needed. Again, I'm not saying that should be the starting four.

Imagine these possibilities:

LM: Pogba, Sancho, Rashford, Martial
AM: Fernandes, Pogba, Sancho, Van de Beek
RM: Sancho, Rashford, Greenwood, Pogba
CF: Cavani, Martial, Greenwood, Rashford

The amount of depth is incredible just by adding one player and retaining a couple.

Fundamentally, I think Solskjær drops Pogba back to CM and starts Sancho, Rashford and Cavani/Martial with Greenwood still finding his way into a more prominent role. However, the effectiveness of that, of course, does depend on who partners Pogba in that deeper role.

If it's my choice in a 4-2-3-1, I start Pogba at LM. His impact higher up is far to good to ignore. However, I don't mind him deeper depending on how Sancho fits in. There are a few dynamics at work there. If I had to choose tomorrow, I start Pogba higher up.
