The French midfielder wants to be payed £200,000-a-week if he is to remain at Old Trafford.
Barcelona and Italian giants, Juventus, are eager to lure the World Cup star away from Old Trafford having been alerted to his discontent at the club.
The player and his United manager Jose Mourinho fell out several times last season.
There were argument over the best position for the Frenchman in United lineup, while he was not happy with comments the former Chelsea coach made about his World Cup displays either.
Pogba’s agent, Mino Raiola, presented an offer from Barca earlier this week which was rejected by United.
According to The Sun UK reports on Wednesday states that Pogba has told United chief executive, Ed Woodward, that it will take a massive new contract offer to convince him to stay.
The Frenchman is currently on £180k-a-week at Old Trafford, but has demanded an enormous pay hike that would give him wage parity with January signing, Alexis Sanchez on £380k-a-week.
Woodward is desperate to keep Pogba at the club, having broken the club’s transfer record to bring the Frenchman back to Manchester from Juventus two seasons ago.
