Just listened to that interview with Aitken and picked up on a few things.
First of all he says most people were surprised he got punted. In reality I think most people were surprised the board actually done it. You would struggle to find more than a handful who honestly felt he should still be there. I'd say 95% of fans wanted a change.
I felt during the interview he kept mentioning the difficulties in keeping a part time team in the Championship, training twice a week etc and saying how tough he had it competing against teams with bigger budgets. What he kind of ignored was how crap this season has been so far and it is actually us who might have a better budger (thanks to the stadium sponsors) than other teams.
He mentions players need longer than 9 games to prove themselves - Aitken was notorious for not playing a settled team, is that helping players prove themselves? (See Gallagher, Calum)
Moans about struggling with injuries and having to play players out of position - most weeks he CHOSE to do this anyway so not sure what the difference is.
Probably more things I can pick holes at but that is all I can remember of the top of my head.
