Violence has stained French football all season. A Nantes supporter was stabbed to death by a driver whose vehicle was carrying Nice supporters before a league game in December. A league game between Montpellier and Clermont was abandoned in October after a Montpellier supporter threw onto the field a firecracker which exploded near Clermont goalkeeper Mory Diaw. Also in October, a league game between Marseille and Lyon was postponed after then Lyon coach Fabio Grosso suffered a serious head injury when the team bus was hit by thrown objects on the way to Stade Velodrome, shattering some windows. Grosso’s deep cut above his left eye required stitches and he wore a large bandage around his head. Inside the stadium, Lyon supporters were also seen making Nazi salutes and monkey gestures. Last month, a violent street brawl involved dozens of ultras before a game between Rennes and Toulouse. French media reports said one Toulouse fan needed hospital treatment for head trauma. Ultras have been targeting buses carrying supporters and there have been more than a dozen attacks this season.
