The BBC do something before every tournament to go on about how bad it is and telling everyone not to go! They did it two years ago for South Africa and they will do it in two years time for Brazil.
I imagine there is still a problem at club level but ask any England fan who went to Ukraine (a lot of my friends went) and they will tell you they had a fantastic time.
They sang a few songs to take the p*ss out of Sol Campbell who was telling everyone on the BBC documentary that if you go you will come home in a coffin!
