Napoli are in talks to sign Bayer Leverkusen goalkeeper Bernd Leno.
Fabio Parisi is working on the deal.
“We're working to bring him to Napoli," Fabio Parisi told Radio Kiss Kiss Napoli.
“There are details to be filed, to be defined. It's a negotiation process, but it's pointless denying he's one of Napoli's top targets.
“It's not something which will be resolved in 24 hours, but it shouldn't take long. The desire is to sort everything before the World Cup, since he's in Germany's preliminary squad.
“There's a release clause of €28m in Leno's contract, but we can negotiate, we can work on it. I'm always optimistic, but that's just my nature.
“The Napoli ownership likes him, as does everyone. We need to work on it, but since we're all serious people the chances are it'll be resolved positively.
“Rui Patricio? Both won't be there, one is the alternative to the other."
