The 23-year-old Netherlands international had been linked with a Serie A switch in January, but he insists that he has no intention of leaving his current club.
Ajax captain Davy Klaassen has made it clear he is not interested in a transfer to Napoli at the end of the season.
The Serie A outfit was keen to sign the Netherlands international during the January transfer window, only for Ajax to rule out an exit halfway through the season.
Recent reports suggest Napoli is ready to return for the attacking midfielder come June, but Klaassen prefers to stay at the Amsterdam ArenA.
