There are many amusing clips of managers losing their temper during a post-match press conference but this one may well be the most angry.
A journalist, referred to by Madjer as 'Mr Djebour', asked Leicester City midfielder Riyad Mahrez a question about the national team's recent performances. The head coach stopped Mahrez from answering the question and instead unleashed his fury in the direction of the national journalist, while the player sat next to him rather awkwardly.
The angry rant is in French, but here's the transcript in English:
"Mr Djebour, the national journalist, you are the enemy of the national team. I say that in public. Everyone listen to me.
"I respect all of you, except him. I don't respect you. Shut up! Shut up! Shut up! Shut up! Retire and let the next generation do the job.
"Next question please."
We don't know what Mr Djebour had said about the Algerian national team in the past, but we're guessing it wasn't too positive, given the ferocity of the reaction from the nation's head coach!
