It's not a new issue, it's a continuation of what we've seen last season. This midfield is extremely inbalanced, basically Matic is doing defending, playmaking, and dribbling in the middle while Pogba is jogging around looking disinterested. Bruno is in a free role, which I think is not helping either.
Bruno's inconsistent passing is frustrating, but I think he's in a bad form and will improve on that.
Pogba though is driving me nuts. He doesn't look like an actual midfielder, it seems like he thinks his role is to stand in the right distance to Matic and defenders. He had a terrible game today (even by numbers), but I think Covid is a valid excuse. However, his performances are not far off what we saw at the season finish.
Many posters say Pogba is not used correctly, and is better higher up the pitch. It changes nothing, except that maybe if he's being played out of position we should consider replacing him with someone who fits the job.
But again, this has all been discussed and I am surprised we're still forcing this setup.
