PAUL POGBA enraged Jose Mourinho after footage emerged of him laughing during Manchester United’s Carabao Cup defeat on Tuesday.

Mourinho looked furious with Pogba during a training session in full view of television cameras this morning.

It’s believed the Special One was left upset when he was informed of an Instagram post uploaded by Pogba after United’s penalty shootout loss at Old Trafford.

The footage shows Pogba laughing in the stands alongside Andreas Pereira.

The pair were present at Old Trafford after being left out of the matchday squad.

Pogba pointed the camera at himself before bursting into laughter, with Pereira also giggling.

Luke Shaw was also filmed striking a pose, and it’s believed Mourinho thought Pogba was laughing at United’s dire situation as they were reduced to ten men.

It led to an icy confrontation on the training ground as Mourinho demanded to know when the post was taken.

However, it’s believed that Pogba filmed the incident before United went behind to Derby.

And a poor wifi connection at the Theatre of Dreams is understood to be the reason why it instead went up after the final whistle.
