The agent of Udinese midfielder Gaetano D'Agostino says clubs are queuing for the Italy international.
The 27 year-old is currently recovering from injury.
Speaking to Tutto Mercato Web, Franco Zavaglia said: "Gaetano now has to think about getting better. We'll see about the future.
"Even if (Udinese patron Giampaolo) Pozzo said that perhaps someone will have to leave Udinese.
"There are at least three teams that want him."
Asked if one of those teams is Napoli, Zavaglia replied: "Let's wait a little longer. It's premature to go into details."
