The Italian club have been busy in the market and are trying to get the best financial deal possible as they seek to complete the €95m signing of Gonzalo Higuaín from Napoli.
Pogba has been continuously linked with a move to Old Trafford as Mourinho looks to complete his fourth fundamental signing and they will have to fork out even more if they want to secure the services of a player who left on a free transfer in 2012.
He could be set for a salary of £11m a year plus incentives at Old Trafford, but Mourinho has insisted he has other options in mind should a deal not be reached.
His agents fee is said to be 20% of the initial sum paid to Juventus and would be paid entirely by United for the third time after two of the Dutch agent’s players, Zlatan Ibrahimovic and Henrikh Mkhitaryan, have already signed for Mourinho this summer.
Pogba left after he suggested he lacked respect by refusing to sign a new contract, but would play a vital role in Mourinho’s side as he looks to get the club back to their former glory days.
