Napoli vice-president Edoardo De Laurentiis says they're looking abroad to strengthen squad.
De Laurentiis accepts they need to accelerate their plans in the final weeks of the market.
He said, "We are talking to many clubs, with Chelsea, Manchester United, Real Madrid, Barcelona because there are players who like Napoli and we are going to see, the transfer market is open until September."
On talk of moving for PSG goalkeeper Keylor Navas, he added: "No. For now we have (Alex) Meret and (Salvatore) Sirigu, for now it's them, then we'll see.
"It's normal that Napoli have to complete the team and we have to look for a striker and a goalkeeper."
