Coming second is ok.
I don't want to win League One as an end in itself. I wanted to win League One because it gets us out of League One. To that end, second will do fine. Winning the play-offs will do fine, and perversely will probably be more fun.
I fully buy into Nicola's ambitions but part of winning is having the maturity and mental strength to press on following a set-back and not having a strop about it and indulging in endless and counter-productive naval gazing.
