Either way, UEFA should take the blame for such stupidity.
Hosting a game of this magnitude in a stadium with a capacity not much over 30,000 was moronic. Of course the neutral zones would be swept with people from either team, what do you expect when yuo give each time 10,000 tickets? And its astonishing that the police and stadium officials didnt think to segregate the Liverpool and Sevilla fans in areas that were originally neutral, but where given to Liverpool due to demand. Apparently they only did this once violence kicked off..... Idiots!
Why was this hosted in a second rate stadium in Basel? It could have sold out 4 times that in a big enough stadium
