The pair clashed during the defeat to Inter Milan.
“I met Kessie yesterday," Gattuso explained.
“I don't hold grudges. I'm not angry, there's disappointment on my part but it's finished now.
“My players know they can dribble with my heart, but respect is needed for everyone. The club acted impeccably.
“During my playing career, I was wrong more than once and I've always paid for it dearly. I've always shown my face and assumed my responsibilities, while the club have always let me feel their weight."
