Napoli boss Luciano Spalletti says he will chain himself to keep Kalidou Koulibaly at the club.

The 30-year-old centre-back has attracted a number of high profile clubs with his performances over the years, including Manchester United and Chelsea.

And Spalletti says he will go to extreme measures to keep his star at the club.

"To keep him I will chain myself somewhere," Spalletti told a press conference.

"Find me something and I'll chain myself there."

It remains unclear if Napoli will try to cash in on Koulibaly this summer, with his contract set to expire in 2023.
