The incident later became public when Marseille included footage of the argument in a season-review documentary celebrating their return to the Champions League.
Speaking about the documentary, he said: "Marseille's decision. I didn't know they'd include it in the documentary celebrating that special season with the return to the Champions League. This episode hasn't changed me. I know where I'm coming from, but I was sorry it might have an impact on those around me. And there's something nobody knows."
Despite the publicity surrounding the dispute, Kone revealed that he has since reconciled with De Zerbi during a recent visit to England.
"A couple of weeks ago, I went to London with two teammates," he added. "I met Roberto, and he gave me a big hug. We talked about so many things, as if nothing had happened. Sometimes social media and the media make everything too big."
