Koulibaly is considered a legend at Napoli after a successful eight-year spell in Serie A which eventually led to his £34m move to Stamford Bridge this summer.
And the Senegal captain has now spoken out against De Laurentiis over his shocking comments regarding African players.
“It’s up to him if he wants to say it,” Koulibaly began during his Chelsea unveiling press conference at Cobham on Wednesday. “But for me, it’s important to always respect everyone.
“When I played there [Napoli], I also played for Senegal. I won the CAN when I played in Naples. It was indeed a difficult moment for them when we went to the AFCON, but we won it and I’m really happy today. We also want the respect of African national teams. We need respect for them like European national teams.
“As the captain of Senegal, I think it’s not a good way to talk about the national team but I respect what he thinks. If he thinks the team can play without African players, it’s “It’s up to him. I think not everyone has the same idea of the club as him.
“I know everyone there. I know the fans and they don’t think like that. I know people who are part of this association and this team who do not have the same idea as him. It’s not the idea of society or the city because the city is very respectful of everyone.
“I think those words are what he thinks and not what the city or society thinks.”
Koulibaly’s reaction follows podcast comments from De Laurentiis, who told Smart Talk on Wall Street Italia in an explosive interview: “Or they sign a waiver giving up their right to participate in the Africa Cup of Nations tournaments. Nations or between the CAN and the South American championships. .
“I never have them (Naples players) available.”
