The Catalan club have had an interest in the midfielder for some time, and have maintained regular contact with his agent, Mino Raiola.
The Barca hierarchy had, however, been willing to sit on a medium-term Philippe Coutinho-style strategy to eventually extract the player, but have been made well aware of ongoing problems between Pogba and manager Jose Mourinho.
While the Wednesday issue that brought so much controversy has now been “fully sorted”, with Mourinho accepting it was just a misunderstanding, there is still a huge distance between the two figures that others at United see as unresolvable.
United sources had previously felt Pogba might be satisfied if Mourinho were to leave, but that stance has now shifted, as there is an increasing acceptance the player - and Raiola - would want a Barca move regardless.
Although United still view the 25-year-old’s marketability as a huge asset, he is no longer seen as completely unsellable, and the club would consider a good bid. Some have floated a price of £140m.
Whether Barca can rise to that level - especially mid-season - is another issue. They are restricted by a huge wage bill, but are being increasingly persuaded of the merits of moving for the player in January, with that marketability being pointed out to them.
