This time around the manager and the core of the team will be the same, this could make a huge difference.
Are you sure? At the moment, only 4 of our play-off final winning starting line-up are still under contract next season: Arnold, Goode, Watson and Adams. That's not enough to be the "core" of the team, especially as Arnold has only played about 10 times for the club. There will hopefully be a few more of that 11 staying (Hoskins, Harriman, Oliver etc) but it's by no means a given. And a number of clubs will be sniffing around Charlie Goode too. And as far as I know Keith Curle hasn't yet resigned either. Perhaps you are suffering from post play-off over-optimism. Easily done!
No, I grew out of Cobblers related over-optimism in the 80's!
I stand by what I said, football faces a tumultuous few months, players and their families will have tough decisions ahead. In contrast, there is a tangible spirit around the club today which was ripped out of the club when Wilder left, who lets face it couldn't get away fast enough.
This doesn't sound like a manager about to leave, does it? Maybe I am wrong?
