#2 Pogba as CAM & Matic as a lone DM
With the arrival of Matic, Mourinho has the flexibility to play Pogba up the pitch and in 5 games he played so far this season, he scored twice and assisted 2 more from a similar role. Pogba can be a good attacking asset than a defensive one.
Pogba has the ability to boss the game and has an excellent understanding with Zlatan which we witnessed last season. His link up play with Lukaku was exceptional in the few games they played together and Mourinho needs to recreate that magic by playing Pogba a little further up the pitch.
Matic will provide the defensive cover that Mourinho needs and United can play free flowing football with Pogba wrecking havoc in the opponents half.
United don't have a specialist no.10 other than Mkhitaryan and Mata, giving Mourinho the obvious reason to try out Pogba. Mourinho has tried him at no.10 in the past and its time for him to give Pogba a long run in that position.
