I've studied a lot of footage and there's no doubt the Russians were pumped full of drugs, not recreational like coke but steroids that give them a feeling of invincibility. W@nkers.
If UEFA don't kick Russia out of Euro 2016 after what's happened then I've lost any repect I had for them or France for that matter. Fighting IN the stadium? That's got to have serious repercussions. Marseille should be stripped of holding any more matches.
