The “gentrification” of football arguably hurt the atmosphere, at least for the bigger premier league teams. There were far more working class local fans singing non stop during the bad old days. If you see older videos the atmosphere was off the wall compared to today (if you want to see truly bonkers atmosphere just look up Boca-River derby or Greek or Turkish football). It was an unfortunate side effect of cleaning up the game and turning it into a tourist magnet.
