Chelsea have been told the price of Senegalese centre-back Kalidou Koulibaly, according to Calcio Mercato.
The Italian news site exclusively report that Napoli would be ready to sell the defender for a price between €60 and €70 million (£53m-£62m).
Koulibaly has been a transfer target for Chelsea for the past two years now, but despite the tempting offers, stubborn Napoli are yet to agree any offers from the Blues.
The 26-year-old is seen as one of the best defenders in Europe at the moment. So far he has played full minutes for his side this season and has helped Napoli to eight consecutive league wins.
The Partenopei are currently on top of the Serie A table and would need Koulibaly for the rest of the season to achieve their dream of winning the league title for the first time since the season of 1989-90.
Chelsea boss Antonio Conte would surely love Koulibaly at Stamford Bridge, but it will be seen next summer whether Napoli still want to sell.
