The movie mogul was spotted man-handling an Azzurri fan outside the stadium.
"I have great respect for all fans and obviously a predilection for Napoli ones," explained De Laurentiis. "I have always said that in me, during a game and in the 20 minutes afterwards, there live two contrary souls.
"There is the soul of the fan who participated in the victory or defeat of his team and the soul of the President.
"Yesterday I was distraught and disappointed by the result as well as the refereeing, which saw a penalty denied that could've changed the course of the game.
"I left quickly and got into the car to go to the airport. A fan suddenly shouted at me through the car window.
"Under the emotional effects of the game, I got down perhaps in an excessively aggressive manner to ask him what he had to complain about. After a few seconds, I got back into the car and was driven to the airport.
"Having arrived in Rome, I immediately contacted the fan via Nicola Lombardo. In the phone call I apologised for what happened and invited him to a cordial meeting in my office."
