Udinese director Pasquale Marino believes Rodrigo De Paul could leave the club in the summer.
Liverpool are the club with the strongest links to the 26-year-old creative midfielder.
De Paul has a contract with Udinese until 2024.
But the Italian outfit's sporting director has refused to rule out selling his star player during the upcoming transfer window.
"He has characteristics that many top clubs in Europe are missing," Marino told Italian broadcaster Radio 24.
"I hope it doesn't happen, but whoever signs him next summer will raise their team to a different level."
