LYON manager Fabio Grosso has shared a photograph of the injuries he sustained during a bus attack on Sunday.
The 45-year-old was left with a bloodied face after stones and glass bottles shattered a window on Lyon's team bus.
The incident occurred while the Ligue 1 side were on their way to face Marseille at the Stade Velodrome.
Grosso was hit by shards of glass from the smashed window and he required emergency treatment after arriving at the Stadium.
Shortly after the incident he was pictured on a stretcher with a severe cut just above his eye.

The match between Marseille and Lyon was postponed after the incident.

"I'm very angry. Our players, our coach prepared for tonight and the fans wanted to see the game played.

"Once the window was broken, other projectiles hit him, just above the eye. There were beer bottles, which hit him on the forehead."
Marseille later issued a club statement to condemn the actions of the fans involved.
It read: "Olympique de Marseille deplores the unacceptable incidents that took place this evening in the vicinity of the Stade Orange Vélodrome, involving the official team bus and buses of the supporters of Olympique Lyonnais.
"The club wishes Lyon coach Fabio Grosso a speedy recovery and strongly condemns this violent behaviour, which has no place in the world of football or in society.
"Because of a handful of thoughtless people, the party planned for this evening has been ruined and 65,000 fans have been deprived of attending a football match.
"The club complies with the decision taken by the Ligue de Football Professionnel and is at its disposal to ensure that the match scheduled for Sunday 29 October takes place at the Stade Orange Vélodrome as soon as possible and under the best possible conditions."
