Marseille chairman Pape Diouf has dramatically departed the club after talks with the French league giants' main shareholder Robert Louis-Dreyfus, according to club sources.
Former players' agent and sports journalist Diouf had been running the club, which finished second in the league last season, since 2005.
The billionaire owner had summoned Diouf to his home in Switzerland for discussions following a very public row about how Marseille should be run.
"After five years of presidency, Pape Diouf will leave his job. I want to congratulate him for his work at the club," Robert Louis-Dreyfus said in a statement, without making clear whether the 58-year-old Diouf had been sacked or was quitting.
"He has been a great chairman who has done everything for Olympique Marseille. From a sporting point of view, he lifted the club to the highest level in France."
Marseille finished second in the league last season, but have not gained any silverware since they won the European Cup in 1993.
