ABC reports the midfielder is ready to hand in a transfer request at Old Trafford.
If that fails, he will reportedly threaten to go on strike and refuse to report for pre-season training in order to make sure he gets his dream move to work under Zinedine Zidane at Real Madrid.
Pogba had an underwhelming season for the Red Devils, but they still want a huge fee of around £160m in order to part with their midfield superstar.
His agent, Mino Raiola, would stand to make close to £20m from the transfer and he is desperate to push through the deal.
But it is believed they are looking to spend no more than £111m plus add-ons to bring the World Cup winner to the Bernabeu.
