PSG president Nasser Al-Khelaifi admits he rapped Real Madrid counterpart Florentino Perez during their recent Champions League showdown.
PSG have been angered by Real Madrid's open pursuit of Kylian Mbappe this season.
And Al-Khelaifi told BBC Sport: "Florentino Perez spoke to me during the Champions League game and said 'we have to get to a point where we can talk to you'.
"I was very hard on him. I said I was happy to talk but if he was going to do things behind my back, I'm not interested."
Al-Khelaifi's comments arrive after previously taking aim at Real Madrid.
"I'm not going to hide it, everyone knows it. We have almost no relationship. I'm not going to go back over what happened," he said earlier this month.
