David Lopez has still not completed his transfer to Real Betis and Marca suggest the deal with Napoli could fall through.
The midfielder had originally been due to sign for his old club Espanyol, but those talks collapsed last week because Napoli wanted full payment upfront.
Betis took over the negotiations and the player has already undergone a medical.
According to Spanish paper Marca, the delays are from the Napoli end and starting to irritate Betis.
