Udinese president Giampaolo Pozzo admits Luis Muriel could be sold.
The striker has been linked with Sampdoria in recent weeks.
"The transfer window is open until the end of January, we will do something," the Udinese patron told Mondo Udinese.
"There will be departures and arrivals. As for Muriel, he has blamed a series of injuries and was unable to score.
"I think a change of scenery might benefit him. But it will, if necessary, be an agreement where we say we don't lose control of him, he's talented and valuable."
