On Wednesday, following the shock League Cup defeat on penalties to Derby County at Old Trafford on Tuesday night, the French star and his manager exchanged stern words with each other as the midfielder made his way on to the Carrington pitch.
In the eyes of the man who partners United with Thai noodle companies, Pogba's commercial pull is worth more than Barca are likely able to spend and it seems the player knows this.
Despite his frosty relationship with Mourinho and reportedly agreeing to personal terms with Barcelona, Pogba stayed at Old Trafford after winning the World Cup for France due to Manchester United declining to sell him in this summer transfer window.
"You want me to say we play a phenomenal match?"
If he is keen to stay in Mourinho's absence, then they will be retaining a world-class player, the likes of which are in short supply at United.
Belgian midfielder Marouane Fellaini levelled the cup clash in the fifth minute of added time to force extra time and penalties.
However, Old Trafford was once again privy to a frantic Mourinho side that was desperate to save face in front of their fans in a night that nearly saw Derby conquer the Red Devils at home.
City was Lampard's last English team after spending most of his career at Chelsea, where Mourinho had two spells as manager.
Mourinho kept going, and Pogba eventually responded and walked on.
Between now and Saturday's game at the London Stadium we hope calms heads can prevail and both Pogba and Mourinho can get on the same page.
Pogba is believed to have been informed in front of team-mates that he does not embody what the club is about, so will no longer act as captain when regular skipper Antonio Valencia is absent.
Things got more hard for United when Romero was dismissed for handball outside his area and Derby capitalised through Jack Marriott, but Fellaini forced a shootout with a last-gasp equaliser.
