The Daily Mail says it's understood that Pogba's agent Mino Raiola is discussing personal terms with PSG who believe they can sign the 28-year-old midfielder for less than half the £89million he cost United in 2016.
Pogba has a year left on his £290,000-a-week contract and has given no indication that he is interested in signing a new one.
It means he will be able to walk away from Old Trafford as a free agent for the second time next summer, having left in 2012 for Juventus.
United must now decide whether to recoup some of that money by selling Pogba before the August 31 transfer deadline or keep the player for another season and risk losing him for nothing.
PSG, one of the few clubs in Europe who could afford his salary, think they can persuade United to sell for around €50m although it's believed there has been no contact between the two clubs yet.
