Chelsea tried to get him last summer but in the end Kalidou Koulibaly stayed with Napoli in the Italian Serie A. According to Premium Sport (via Itasportpress ) , Napoli and the player's agent have an agreement in place:. It is not a secret that Antonio Conte's Chelsea like him a lot as the Italian coach is looking to add some quality to his back line. Here is what his agent had to say in an interview with MondoNapoli (Via Itasportpress): " Koulibaly? The transfer maket is long as it will be open until August 31st, something might happen before then... . Chelsea? They are a world class team that many players would like to join but I don't want to talk about this now ....".Koulibaly's interest is there as it remains to be seen if the Blues would be willing to offer Napoli 60 million euros for their star defender. In the Italian Serie A, Conte's number one choice is still Leonardo Bonucci but it won't be easy to pray him away from Juventus.Jean-Luca Mascaro (@CalcioNews89)
