Napoli sporting director Cristiano Giuntoli has confirmed that striker Gonzalo Higuain is not for sale.
Giuntoli revealed that a number of Italian clubs have made an approach for the Arsenal, Chelsea and Manchester United target.
But he also insisted that Napoli have no intention of selling the striker during this summer's transfer window.
"Some Italian clubs from the north have taken an interest, but he will stay with us," Giuntoli told Sportitalia.
"Now the job is to reinforce both the midfield and defence.
"We want to touch the attack as little as possible."
