The midfielder uploaded pictures of him appearing to talk in a hushed manner to Kylian Mbappe and Antoine Griezmann from France's friendly with Germany on Thursday night, and asked fans to caption the snaps.
Pogba's future at United has been in doubt for some time and following the game at the Allianz Arena he said: "My future is currently in Manchester.
"I still have a contract. I'm playing there at the moment, but who knows what will happen in the next few months?"
And the backlash was swift.
One United supporter replied: "Paul why are you being a p**** to the United fans that have stayed loyal to you? I love you brother but you aren't showing yourself in a good light at all. If you want to leave then leave but don't let your agent rub our club through the mud in the process."
Another fan posted: "I hope you will read the comments and advise yourself accordingly. Fans are losing it with you. Better sort yourself out start playing well or get of the club. You're too small to think united cannot do without you. Jose is winning the fans and you're losing them."
