The 25-year-old striker has expressed his desire to leave the club this summer, but Juventus wants to receive a compensation package.
Vlahovic's contract with Juventus is set to expire in one year, and he has asked the club to release him from his deal with a €10 million severance payment.
However, Juventus has rejected this request and is instead asking for a transfer fee of €25 million for the Serbian striker.
The club may be willing to negotiate the price, potentially lowering it to €20 million.
Manchester United is keeping an eye on the situation as they look to strengthen their forward line.
