Guingamp president Bertrand Desplat has launched a scathing attacking on Dynamo Kiev's supporters after his side's Europa League match in the Ukraine was disrupted by violent scenes.
The away fans were forced to vacate the stadium after a group of masked home supporters fought their way past stewards in an attempt to clash with their French counterparts.
The incident resulted in the match being halted for almost a quarter of an hour while the players were holed up in the safety of their dressing rooms.
"I saw a stadium at war with rabid dogs that wanted to fight," Desplat told RMC.
"There were 11 heroes in Guingamp colours on the field because organising a match in these security conditions, when the safety of a certain group is not assured, is catastrophic for football.
"These are not fans, they are militiamen. Restarting play? How do you expect the players to focus on their game? It was extremely dangerous. This match could only have happened in Ukraine under these conditions."
Guingamp lost the second leg of the last-32 tie 3-1 and bowed out of the competition 4-3 on aggregate,
