Hmmm, I wouldn't say he was overrated, as I never rated him at all. I recall everyone pretty much blamed him for us not winning the league the year we signed him. I thought he was a carthorse, and he did nothing to change my mind. The only good thing about him was he his name fitted in at the end of one of my favourite Villa songs to sing when pissed up in the pub!
Alot of money with very little return though.
As good as GT was for us during his first spell as a manager, it still puzzles me that we signed Cascarino rather than his strike partner at the time.
