Despite the signing of Bruno, Pogba is above everyone in midfield, the quality gulf between him and Fred/Mctominay/Matic was huge.
Everyone seems to forget that Pogba was playing in deep-lying playmakers role in the early season before he gets injured, that's a role he plays for France during the world cup and was the best progressive midfielder in the competition
We signed Bruno to replace Andreas/Lingard in XI, not Pogba. Pogba will replace Matic when he is fully fit, he has more things to offer us than Matic and improve us offensively.
Let's see what Bruno can offer to Pogba, he can offer to cross that Pogba can make a powerful run to the box to attempt a header, he can play direct pass together with Pogba, he can offer set species/corner to Pogba, he can offer an off-ball movement like Mata to Pogba, he can offer to take burdon off Pogba's creativity so they cannot mark Pogba.
Bruno and Pogba are intelligent, they can contribute a lot of points for us, when they play great, we'll be far more dangerous.
