The 25-year-old who just returned to training a few days ago was a surprise starter for United in their 2-1 win over the Foxes, where he scored the first goal.
Pogba said "everybody was on the same page" in the France dressing room, from Deschamps to the staff and players - that has not necessarily been the case at United with several players at different times singled out for public criticism by Mourinho.
But it was when he was asked whether he was happy at Old Trafford that Pogba gave a rather extraordinary answer.
While United have denied that occurred, Wallace feels there will be only be one victor if the club's hierarchy have to make a decision between keeping the player or their manager.
But in comments attributed to Pogba in today's British newspapers, he says: "There are things I can say and there are things I cannot say. otherwise I will get fined".
"I always give my best for fans, my team-mates and for people who trust me". They took the lead early in the third minute via Pogba's penalty, but then couldn't maintain their grasp on the game, and allowed Leicester to dictate the play, although they never looked like scoring.
United didn't sign a single player in the summer transfer window after July 3rd, and Mourinho spent a good chunk of the preseason complaining about not getting the support he desires in the transfer market.
He is anticipating a hard season as a result, and criticised the club's board for failing to deliver on plans he had put in place "for many months". Transfer deadline day came and went, with no new additions and this Mourinho hit out the club board for not giving him the ingredients that he believes he needs to cook. The manager has names but after, it's how we feel.
Speaking to Sky Sports after the game, he explained: 'I think football is changing, and probably football managers should be called now more head coaches.
"When you have everybody with you, everybody next to you, you know they want to fight for you, obviously it's going to be easier", he added.
"Forget the name, the history, the shirt, every match is hard".
Mourinho intimidated the way United operated - and the amount of power he wielded - would be shifting following the club's Friday night win over Leicester City.
