Yeah, but at the same time, we've had a bad reputation for not being patient with managers so there was probably a damned if you do, damned if you don't situation going on. And it's far from cheap firing managers mid-contract, so you can't do that 2-3 times a season.
But there's no culprit here. You cannot blame a manager for not having the tools, but you cannot wait for ages for him to turn a rock into gold without knowing how to do it either. This is just a proper brick show season where the stars have aligned with the FA to see Spurs relegated, because Spurs don't do proactive.
