Udinese vice-president Stefano Campoccia admits Napoli have made an approach for Rodrigo de Paul.
Campoccia says De Paul is wanted by Napoli president Aurelio de Laurentiis.
He said, "De Laurentiis has made a transfer enquiry for De Paul, but he must understand that we are talking about an expensive footballer.
"When I see De Paul play, I reconcile myself to football."
De Paul's contract with Udinese expires in 2024.
