As soon as the fan base realise we're not a Premier League Club and won't be again, then well have a better chance of progression.
We may in the future spend a season or two in th PL but we're so very very far behind the curve now we'll never be a PL club again.
Unless of course we get a Red Bull / Mad Billionaire scenario but even then the way funding is controlled and penalised by EFL/EPL for 'new money clubs' even these examples may not be enough.
