United forum says they have tried him in every position and he doesn't fit anywhere.
Never with a proper midfield though, that's my point. You can't succeed with a Fred and McTominay as you deep central midfielders lol. Either way I think the issue is more his consistency rather than position, considering Bruno is a monster regardless of his partners in midfield. He elevates the team rather than begging questions such as "he needs this, and this, and that to perform."
