I think that is the closest we will get to hearing his actual opinions. He was very careful in his choice of words / phrase but said enough for us to establish his real feelings. He's still employed by the club, so its difficult for him to come out in public.
His contract is almost up do mate that's why he's chosen now as the time. Not like he'd say it after a victory is it.
Definately confirms he will not be here next season, and I'd extend that to being in the club altogether and not just te managers job.
