Lyon coach Fabio Grosso was reportedly struck by a stone

According to Le Parisien, the Italian legend was hit by shards of glass and required medical treatment.

He was left bleeding, with knowledge of his injuries unknown at this time.

One of his assistants, Raffaelle Longo was also reportedly injured.

When the bus arrived at Marseille’s stadium, Grosso appeared in the Velodrome tunnel heading to the changing rooms.

He was seen with a bandage wrapped around his head.

In another photo, Grosso was also spotted on a stretcher with an open gash above his eye and his hand covered in blood.

So fare Lyon and Marseille have yet to make comment.

Trouble at games involving Marseille is nothing new.

Only last month riot police were hit by an explosion when fans of the French club and Ajax clashed outside the Johan Cruyff Arena in the build-up to kick-off.

One video showed hundreds of Marseille fans, all dressed in black, marching up a street before running at Ajax supporters.

In another fans could be seen throwing punches next to food stalls outside the stadium.

Riot police got involved in an attempt to separate the two groups, which resulted in them being the target of violence.

Police were forced to dodge an explosion that appeared to be a firework, next to a van they had used to create a barrier between fans.

The NL Times report 12 Marseille fans were arrested – six for carrying a deadly weapon, six others were reportedly arrested for loitering.

Marseille fans were in the spotlight last year after treating Tottenham to a hostile reception for their Champions League encounter.

Flares and pyrotechnics were set off outside the Stade Velodrome prior to kick-off, while fireworks exploded near the team hotel during the middle of the night.

A year before Neymar was pelted by missiles as he went to take a corner at the ground, forcing riot police to shield him from the aggressive Marseille contingent.
