The two spent a year together at PSG, with Stambouli eventually moving on to Schalke in the summer of 2016.
Ibrahimovic is known in football for his over the top personality, and Stambouli's comments will only further that impression.
"We were at physiotherapy and news was on TV," the 27-year-old told Goal.
"Zlatan asked me to translate it because there was something about him on.
"So I explained that they said that Zlatan is the King of Paris. I thought he would be happy about it, because it's great that the people love him so much. But he was different. He was very angry and shouted at me: 'What the f***? I'm not the king, I'm god'. This guy is totally crazy."
