Marseille will be banned from the next European competition they qualify for should they fall foul of any UEFA regulations in the next two seasons.
UEFA has taken a dim view of the behaviour of Marseille fans during the 2017-18 Europa League campaign, citing four matches where rules were broken.
The games in question all came in the knockout stages of the competition, starting with their last-eight meeting at home to RB Leipzig, before both legs of their semi-final with Red Bull Salzburg and the final against Atletico Madrid in Lyon.
Marseille were charged with crowd disturbances, acts of damage, setting off of fireworks, throwing of objects and a delayed kick-off by Europe's governing body.
