Cagliari's owner Massimo Cellino says midfielder Andrea Lazzari can move to AC Milan - if the price is right.
The Cagliari president had previously expressed an intention not to sell anyone in January as his club sit in mid-table in Serie A.
But, following an approach by Lazzari expressing his desire to re-join former boss Massimiliano Allegri at the San Siro, Cellino says he can leave the club if a suitable fee can be arranged.
The Cagliari president also believes keeper Federico Marchetti will go out on loan to Genoa, while there have been enquires concerning striker Alessandro Matri, but no firm offers.
Cellino told to Sky Sport Italia: "Lazzari wants to go to Milan. Two days ago he came to me and told me that he would be a dream to reach the Rossoneri and Allegri.
"I replied that I'll please him if Milan satisfies me. I cannot remain without money and with one player less in the roster. Now it is for me to see how much the Rossoneri are interested in Lazzari."
Concerning Matri, he added: "Many have asked about him, both medium and high clubs, but nothing concrete.
"Marchetti? (Genoa's owner) Enrico Preziosi likes him. I would have preferred to talk about it after this season, but now I'm convinced he will go on loan for six months to play. "
Lazzari's agent Stefano Zambetti also believes a deal can go through.
He told calciomercato.it: "Andrea to AC Milan? There is a willingness of all the parties, now, I presume, the clubs will speak to each other. And I suppose also that this week there may be contact with us."
