It's what would previously have been called a transitional spell/season. Nowadays it's a disaster and someone must pay.
I'm no psychologist but to me it suggests their confidence is shot to pieces. They start off as if they're going to end the run then as soon as they lose a goal it's 'oh God, here we go again'.
I read Thistle and Motherwell fans saying the same thing happened to them after having to play at least one of the Old Firm numerous times in a very short period and getting stuffed so it's not a unique situation. Ours has just gone on longer. We'll recover and we'll be fine.
