The Frenchman helped inspire the Red Devils to an incredible come-from-behind victory at the Etihad to briefly spoil Citys title party, though defeat at home to West Brom just a week later saw Pep Guardiolas team crowned champions.
Pogba scored twice at the Etihad in what appeared to be a defining performance that could reignite his United career.
But now The Sun report that, in the middle of Pogbas heroics, his relationship with Mourinho actually took another knock when they clashed during half-time.
It is claimed that Pogba was singled out for his poor performance by Mourinho at half-time, though the £89m man did not appear to listen to his managers criticism.
Instead, Pogba only incensed Mourinho further by muttering under his breath as he was scolded in front of the rest of his teammates in the away dressing room at the Emirates.
Players were then left confused at full-time when Mourinho praised Pogba after his brace and claimed that he would have been his man of the match even if he had not got on the score sheet.
Pogba is said to be bemused by Mourinhos inconsistent attitude towards him and their relationship is strained as a result, even more so after he was subbed off inside an hour against West Brom.
Mourinho is believed to be willing to sell Pogba this summer but the Frenchman is keen to stay and win silverware at Old Trafford, while Real Madrid are lurking with intent despite Pogbas relatively poor form this season.
