Napoli are battling to keep Kalidou Koulibaly away from Premier League suitors this summer.

Corriere dello Sport says Liverpool, Chelsea and Arsenal are all eyeing Koulibaly.

Chelsea lead the chase for the Napoli defender, who is valued at around £45m. Koulibaly has played a big part in ensuring the Italian side have conceded just 20 goals in 30 games this season.

Napoli are willing to do “whatever is necessary" to keep him in Naples, but a move from Chelsea could spark a bidding war with Arsenal and Liverpool also interested.

Koulibaly resisted a move to Chelsea 18 months, but could now be persuaded to move to London.
