Pogba, who has led the side out in three games this season, was told about his demotion before Tuesday night’s defeat by Derby County.
It is understood the club’s senior officials, don’t have any intention of asking Mourinho to rethink his decision.
“If you’re a captain or vice-captain, you’re more often than not speaking on behalf of the players, and there is nothing wrong with giving the manager your thoughts. But this shouldn’t be done in the media – it helps nobody to be played out in public!
“In modern football, players are very powerful; they are the stars of the show. I’m really surprised it has got to this stage. This sort of thing really needs to be kept in-house. You’re all grown-ups; figure it out in the dressing room.
“For Mourinho to have gone as far as removing the vice-captaincy, Pogba must have provoked him – whether it was the comments after the Wolves game or something else. But these arguments affect everybody else and start having an impact on the pitch,” Berbatov told Betfair.
