The chavs playing up in Amsterdam won't be on the plane to Russia. It won't stop England fans with no interest in a row being set upon or ambushed though.
Before all the Russian Ultra hype started, in 2007 for the qualifier in Moscow, groups of English were being picked off in broad daylight by Russian lads. In fact the group i was with got attacked at a tube station, with no provocation, by a Spartak Moscow firm.
If you think the police will look after you, forget it. We heard several tales of Russian coppers snatching passports and demanding money to hand them back.
My advice is watch it on the TV, don't give them a penny of your hard earned. It isn't worth it. The media may try and hush it up but there'll be violence at the tournament without a doubt.
