Former Italy captain Fabio Cannavaro admits he's a fan of Napoli defender Kalidou Koulibaly.

The Senegal international is being linked with Barcelona this summer.

Cannavaro, who played for Napoli, said: “Kalidou is a strong defender and there aren't many players like him.

“At the same time, I understand (president Aurelio) De Laurentiis as it's not easy to balance the books. Sometimes one wants to save money, but in some situations, the risk is to spend more."

Koulibaly has a contract with Napoli to 2023.
