The French midfielder left Old Trafford in 2012 after refusing to sign new deal with the Red Devils when Sir Alex Ferguson kept him in the reserves.
Now one of the top players in Italy, Pogba is the subject of a £35million bid from new United boss David Moyes however the playmaker is set to immediately dismiss the chance to return to the North West of England.
Real Madrid are also keen on Pogba and the 20 year old would be happy to enter talks with the La Liga leaders.
After spending big money on the likes of Gareth Bale and Isco last summer, Madrid are set to do the same at the end of this season to pile the pressure on underachieving Barcelona.
United will still make a move for Pogba , but Moyes will have to convince the France international that a return would be good for his career.
