The bad old days of the late 70's and 80's were swept away during the 90's when the stadiums were forced to be rebuilt as family-friendly all seater arenas, this and the wider popularistaion of the game amongst the middle classes and vastly increased ticket prices have meant that the more unruly elements are no longer as evident at top flight games (Premier League) as they used to be. A lot of people would argue that the experience and atmosphere of attending a game is rather sanitised compared to what it used to be as a result of these changes.
However occasional trouble does still exist in the lower leagues and sometimes during derby games as well, which many police forces insist kick off at lunchtime so that fans don't have time to get rowdy down the pub beforehand. Ironically our authorities are now consulted by European ones on how best to tackle the problem, not that it's been eradicated over here.
With the exception of the recent West Ham v Milwall incident "Football Hooliganism" hardly gets a mention in the media at all, well unless you count those rubbish Danny Dyer type films.
