The France international, took to the social networking site at around 11am to answer questions posed by Red Devils supporters.
One fan asked when his alias, Agent P – who helped land Romelu Lukaku – was getting back to work in the transfer market.
Pogba replied in a cheeky manner, telling the supporter that he “never sleeps”, suggesting he is always on the look-out for new players.
The Frenchman gave himself the nickname moments before Lukaku was confirmed as a Manchester United player this summer.
Pogba was on holiday in Los Angeles with the Belgian – who he has been friends with for some time – where United would later have their pre-season tour.
The 24-year-old posted videos and images of the duo having fun to his Instagram page before adding the hashtag ‘Agent P’ to one particular clip.
The footage showed Pogba congratulating the Belgium international on his move to the Old Trafford club – before it had been officially announced.
Needless to say, Red Devils supporters were chuffed with the efforts of their record signing, who helped United land the striker from under the noses of Chelsea.
Jose Mourinho’s men are still in the market for another player before the transfer window slams shut at the end of the month.
In recent weeks they have been linked with Inter Milan winger Ivan Perisic, although a move for the player appears to have recently broken down.
Still, Pogba is on the look-out, and United fans are feeling rather optimistic…
