Chelsea boss Antonio Conte tried to sign Napoli defender Kalidou Koulibaly last summer but had a £58million bid for the Senegal international defender rejected by Napoli.
Despite Koulibaly signing a new five-year deal in September, the agent of Koulibaly, Bruno Satin, has refused to rule out a Chelsea move for the defender this summer.
“Chelsea were interested but then they signed David Luiz and you also have John Terry and Gary Cahill at the club so there is a lot of competition there,” Bruno Satin told Radio Kiss Kiss Napoli.
“So we will see what happens. A lot of the improvements that Koulibaly has made in his game has been down to the coaching of Maurizio Sarri.
“Whatever happens in the future will depend on the president [Aurelio De Laurentiis] and whether or not he decides to evaluate any offers that may come in.”
Last month, Koulibaly admitted he could leave Napoli at the end of the season.
“It would make me happy to come and play here, but I now I have to go to Napoli,” Koulibaly said.
“In the future you never know.
“Now I concentrate on my club and we will see next season what I have to do.”
