The United midfielder was absolutely fuming with Tierney waving away his penalty appeals in first-half stoppage time.
Anthony Martial cut in from the left and curled a shot goalwards that Pogba was adamant hit a defender’s arm.
He immediately threw both hands up in the air to appeal for a spot-kick – but Tierney wasn’t interested.
Pogba couldn’t believe his appeals were dismissed and confronted Tierney at the next break in play.
In the end, the decision didn’t matter. United came from a goal behind to win 2-1 after Marcus Rashford’s late winner.
Not that Jose Mourinho, whose side have taken ten points from their last four games, thought they deserved it
He said: “I told Eddie Howe it should be 5-1 at half-time so at least I recognised they were the best team by far at half-time.”
In the end Bournemouth only had Callum Wilson’s seventh goal of the season to show for their first-half dominance.
Mourinho added: “I said at half-time I was the luckiest manager in the Premier League in a half when it should be like 5/6-2.
“We were defensively awful. People watching this game will not believe how hard we worked this week.
“The first half was a disaster. The second half was much better and we deserved to score before the 92nd minute.
“It is fantastic to have this feeling that the game is not over. We have fantastic character and the heart.
“Even after missing chance after chance they kept going. That’s a fantastic quality for the team.”
