The France international is a top target for Zinedine Zidane this summer and the Frenchman has demanded the club break the bank to sign the 26-year-old.
Los Blancos have already expensively overhauled their squad, but they view Pogba as the missing piece in the jigsaw.
United aren’t averse to doing a deal, but they want a hefty return on their initial £89m investment from two years ago.
A £180m bid will be needed to prise him away from Old Trafford as Manchester United dig their heels in.

“Real Madrid are desperate to sign Man Utd ace Paul Pogba”
Nevertheless, according to reports in Spain, Real have already dismissed three alternative options.
Zidane had been eyeing Tottenham ace Christian Eriksen, Napoli midfielder Fabian Ruiz and Ajax playmaker Donny van de Beek.
Eriksen, who joined Spurs in 2011, has also been mentioned as a potential replacement for Pogba at United.
Ruiz is a rising star at Napoli and will be offered a new contract by Carlo Ancelotti to ward off poachers.
Van de Beek, meanwhile, was an integral member of Ajax’s exciting young side that reached the Champions League semi-final.
Despite the other talents up for grabs around Europe, it’s suggested Real aren’t ready to compromise and will now push the boat out for their No.1 target.
Club supremo Florentino Perez wants a deal done imminently, though.
He’s concerned that as the August 8 deadline looms, United will be increasingly reluctant to sell.
Pogba’s departure could leave a gaping whole in the Red Devils’ engine room and Ole Gunnar Solskjaer wants a replacement lined up.
The wantaway star’s agent, Mino Raiola, has claimed his client has been keen to leave for a while.
“The player [Pogba] has done nothing wrong,” the Italian said.
“He has been respectful and professional in every way and always.
“The club has known his feeling for a long time.
“It is a shame other people only like to criticise without the right information, and I am also sorry that the club does not take any position against this.
“Hopefully there will be soon a satisfying solution for all parties.”
