The Senegal captain has now spoken out against De Laurentiis after complaints about their international commitments.
“It's up to him if he wants to tell this," Koulibaly began at his Chelsea unveiling press conference at Cobham on Wednesday. “But for me, it is important to always respect everybody.
“When I played there [Napoli], I also played for Senegal. I won the AFCON when I was playing in Napoli. It was indeed a difficult moment for them when we went to the AFCON, but we won it and I am really happy today. We just want respect for the African national teams also. We need respect for them like the European national teams.
“As the captain of Senegal, I think it is not a good way to speak about the national team but I respect what he thinks. If he thinks that the team can play without African players then it is up to him. I think that not everybody has the same idea of the club as him.
“I know everybody there. I know the supporters and they don't think like this. I know some people who are part of this association and team who don't have the same idea as him. It is not the idea of the society or city because the city is very respectful to everyone.
“I think these words are what he thinks and not what the city or society thinks."
