The PSG chiefs were furious after their side blew a 2-0 lead after Karim Benzema scored a hat-trick. The pair followed the match referee, Danny Makkelie, into the dressing room after the loss. The incident was described as "frankly unpleasant" by reporter Monica Marchante, according to El Partidazo de COPE.
And now, according to L'Equipe, an excerpt from the referee's report quoted by Onda Cero, Al-Khelaifi and sporting director Leonardo: "Behaved aggressively and tried to enter the referee's dressing room.
"When the referee asked them to leave, the president hit a piece of the assistant's equipment, breaking it."
Marca added that Al-Khelaifi stormed into the wrong room, and ended up confronting Real Madrid's match delegate Megia Davila.
"He then had to be removed with difficulty and several people had to intervene," the report added.
Speaking after the game, Leonardo said it was important not to 'throw everything in the bin'. "We shouldn't throw everything in the bin," the Brazilian told RMC Sport after the match.
"We shouldn't start from scratch after every loss. The objective is to win the Champions League, and until half-time we were fine.
"We have to look to improve this team and maintain morale to play in Ligue 1 and to finish the season well. We should stay together. Pochettino is still part of the project for this season. It's not the time to think about that."
