Gennaro Gattuso is leaving the club after less than five months in office. The Italian was fired after a series of poor results.
He will be replaced by Jean-Louis Gasset. The move was announced by the club in a press release on Tuesday. The club is currently 9th in Ligue 1, one point behind second-placed Marseille. It is the second time in three years that the club has lost a game in the Champions League group stage. The previous defeat was in the quarter-finals in April.
