The weird thing about Villa, compared to say Spurs or Everton, is that our modern successful eras have come sort of at a time when English football was utterly dominated by other clubs- Liverpool and Forest late 70s/early 80s and Man Utd in the 90s. We have never had an era where we became successful at a time when the field was clear because of the collapse of other dynasties ( Man Utd somewhat fortunate Liverpool were a mess in the early 90s, you could say Liverpool and Man City have been somewhat fortunate that Man Utd post Ferguson have been a bit of a mess).
I honestly think we are on the brink of something and yet again it will involve us having to burst through a really tough field of teams to win honours. That said, if a Man City were to implode in coming years who is to say the planets wouldn't align for a tilt at the league championship?
