the cynic in me says that weds/thurs will pass off without any trouble under the treat of expulsion.
If any troubles do occur then full investigation should take place with the swift action taken. Based on the 'facts and figures' being banded around on here and also in the press it should be very easy for authorities to get a clear picture and take the necessary steps to ban whichever nations fans are causing such ridiculous scenes
Unfortunately with England, Russia, Slovakia & Wales all in the same city , I fear it will get worse. The Russians don't care, the English will fight back...
