It was shit because we were shit
Predominantly because a certain individual poisoned the atmosphere at the club by trying to make us lucky and then choosing to sack (mid season!!) the best manager we'd had for a long long time because he was more popular than himself, and oh yeah he had the audacity to be the first manager in history to buy a dud (who's now banging them in in the Champions League)
That said I'm with you in not wanting to go back but for me it's until he's gone. Can't be bothered for any more of the national humiliation he brought on the club.
Has any promoted club ever got it sooo wrong!
