Good video by the BBC on how Villa went from Europe to relegation, or 'Rotterdam to Rotherham' as the fans are putting it: http://www.bbc.co.uk/sport/football/36062892
It doesn't cover all of the things we've been through in recent years though - captains getting cancer (Petrov), important players forced to retire early (Laursen, Petrov) captains lying to the fans (Barry, Delph), players getting high (Ireland, Grealish, Agbonlahor), nightclub brawls, going months without scoring goals, 8-0 defeats, no money, worst home form in the history of the club...
'Death of a thousand cuts' is quite fitting. It's been a miserable few years.
