Parisi doesn't believe United would be willing to sell Pogba at a loss.
He told RMC: "Tell me why Manchester United has to resell Pogba for less than the €120m paid a few years ago.
"I do not think Juve would make such an investment, with the salary the Frenchman now has."
Parisi also believes Tottenham midfielder Mousa Dembele will go to China in January.
He added: "I do not know, Dembele of Tottenham could leave to go there."
