With reports of hooliganism, fights, racist behaviour and now, a murder in the news, this tournament could end up being remembered for all the wrong reasons.
UEFA/FIFA will probably turn a blind eye on most of this as unfortunately, the main thing they care about is the money. Morals have been thrown out the window and with Russia hosting the World Cup in 2018, things could potentially get worse if proper, authoritative action isn't taken. I'm aware that it's only the minority who are causing trouble but even a small group of people can ruin everything. As it stands, the only course of action I can see UEFA/FIFA taking, if the behaviour gets out of hand, is to just fine the two FAs and that's quite a weak response imho.
