Yeah best manager on the planet, you hear that all the time.
Most would accept quite happily the sun don't shine out his arse Mizer. There is a complete myth that Calderwood is immune to criticism or that he hasn't made big mistakes for some, it really is utter bollocks and I reckon most don't need to have it pointed out where the sun doesn't shine from.
But to suggest that a manager should be dumped on the basis of one bad run in any season is pretty ridiculous.
