Pereira is never getting on over Pogba mate. He'll get his mins, but he knows his place in the line. When we're playing weak opposition, 4-2-3-1 with Matic/Herrera & Pogba is fine. When we play 4-3-3, it's likely to be against tough opposition/tricky away games, in which Matic-Herrera-Pogba is our strongest midfield. Pereira is an offensive CM, like Pogba, but Pogba levels ahead. I do like him, and he will get mins, but don't be surprised to see him left out of quite a few PL match day squads.
Not sure we should be trying to get Pereira in the Pogba position. He's more suited to further up the pitch maybe no.10 or even on either wing.
I realise it's going to be hard for him, but honestly, if we're waiting for him to succeed Pogba.. we mayswell just sell him now. Pogba has a long, long time at United.
