It's weird though because Villa is in a weird middle ground where they spend far more than most non-big 6 teams and have a net spend higher than that of Liverpool and Man City (But that's also because these clubs have won trophies, improving their net spend).
As well, under Unai Emery, they could easily build back the pre Premier League days of Villa if they win a trophy or two as they have a ton of history, very large fan base, and decent ownership. As a result, Villa, and Newcastle as well, are in weird spots as they are very obviously growing extremely fast.
This season atleast. Last season I think it was Brighton? Wolves have had terrible ref calls against them 3~ times already. Media just doesn't cover it frequently because it's not a large team like Arsenal or Liverpool.
Also, Gary O'Neil hasn't been as out spoken as Arteta or Klopp, but it's very evident that Wolves have been on the receiving end more than any other team. It's a shame that managers who were so outspoken previously aren't backing Wolves.
