IMO blaming the injury crises and not Postecoglou for the 17th position finish, is the same as blaming the injury crises and 16th (I think it was) position and not Frank.
So a rational argument could be made that Frank was as good as Postecoglou, IMO he was a bit worse but there is a rational argument that could exist regardless.
It seems all the excuses that were made for Postecoglou, Frank wasn't entitled to. Maddison and Kulusevski are probably the best two attacking players at the club.
Frank didn't win a trophy but the team was doing well in the Champions League, which is regarded as a tougher competition than the Europa League.
Seems like people want to make excuses for Postecoglou's league position but refuse to make the same excuses for Frank.
A mental health professional, could well find that deranged, and like

once said, Postecoglou has brainwashed the supporters, so I assume the supporters he was referring to includes you.
