The 25-year-old is pushing for a move away from Juventus this summer and the feeling appears to be mutual.
Vlahovic is understood to have requested his contract at the club be terminated, but the Serie A giants are determined to get a transfer fee for the striker.
He has just one year left on his contract at the club and he and his agent requested Juventus terminate the deal with a €10 million severance package, but the club rejected it.
According to Calciomercato, the club has set an asking price of €25 million for the Serbian but could be negotiated down to €20 million.
Man United are understood to be keeping tabs on the situation as they seek to bolster their struggling forward line.
