Livorno president Aldo Spinelli insists Marco Amelia will only leave the club on their terms.
Amelia has been strongly linked with a move away from Livorno with the likes of Liverpool and Milan reportedly interested in him.
Livorno are hoping to keep hold of Amelia and have held talks about extending his contract.
Amelia is believed to be weighing up his options and Spinelli has warned him he will only leave if the offer is right for Livorno.
"Amelia can leave in January only in case of a really favourable offer for Livorno," Spinelli told Guerin Sportivo
"We have no difficulties in keeping him until June, so we will have to evaluate with attention the offers when the market will reopen."
Spinelli also rejected suggestions that talks have taken place with Milan over a possible move for Amelia.
"He can be liked by Milan, but I want to underline that no negotiations have been opened," added Spinelli
"Before taking a decision we will evaluate also with him the possibilities of a move."
