Football fans generally, at all levels, have always been like petulant children. No matter the context; and let's face it there are absolutely mountains of that here, they are only ever a few games from stamping their feet and throwing the toys out of the pram.
I mean, what are we saying here? That the manager is holding us back? From what exactly? Only being relegated by 10 points instead of 15? Even if we were dumb enough to appoint anyone else soon, what sort of transformation are you expecting? And would you give the new guy long before the same old clichés were coming out, because let's face it; the defeats are going to keep coming regularly.
Depending what sort of position we're in nearer the end of the season in terms of morale, finances, long term strategy and embargoes, then that could be a different matter. But even then, Pedersen would be likely getting judged on a ridiculously unfair set of circumstances.
