Sounds slightly defeatist and accepting of the inevitable to me, referencing his sacking at Valencia without being prompted to. That's quite an insight into his thinking.
True, sounds like, 'why should i worry, i cant get the team to play how i want,' its not my fault,
also the not accepting the negativity shows how much passion he has, and that same passion has rubbed off on the players.
I hope/wish he can change his mindset, and that translates onto the pitch, For that, he needs to start getting Goodison behind him.
I feel he referenced Valencia due to not having enough time there, but sub consciously he fears that we will become worse than when he was at Valencia.
