My worry is that with all this going on Uefa will need to expell a team from the comp to calm things down. No prizes for guessing who that will be unless the bolshies do us a favour at the Wales match.
UEFA need to kick this one upstairs to FIFA for a review of WC18. The Eastern European thugs led by the Russians could be lethal. Russian policing could also be a concern since they are becoming paranoid about their treatment over their cheating at the Olympics.
The next World Cup in Russia is going to be horrendous. If it happens at all. If the Russians keep pushing in the Baltic states, we could be at war with them before the World Cup even kicks off.
