Kepa was dropped and replaced by Caballero for the win over Tottenham - the decision made after his revolt during the Carabao Cup final defeat to Manchester City.
Caballero told RMC: "Everything is fine between Kepa and me. We talked about the incident and it was good. He learned and the whole team too. We are more united than ever even if we are mistaken as human beings.
"But there were people to help us. As goalkeepers, we must be united. It was a strange situation. We must overcome it. I have to live with it, we all have to do so.
"Everyone has learned. This brought something positive to the team's atmosphere. I hope the fans will forgive Kepa."
