So if we finish 7th he should keep his job, 8th he loses it?
You have put me on the spot here, but I'd say if we miss out on European qualification by finishing 8th or lower for the second season running, assuming we won't win either of the cups, I would think it would be sufficient grounds have a serious review of his position at the very least, not least considering who might be available as an alternative.
I prefer stability and would like to see him see out his contract, but we can't be afraid of change either. Spurs did get through their fair share of managers before hitting a winning formula, and regular managerial changes didn't affect Chelsea greatly until recently perhaps, not that they are the best comparison for us.
You don't move someone on for the sake of it, particularly given our recent history either.
The problem is drawing an arbitrary line in the sand somewhere, as cruel or as generous that appears to be, and how much time is time enough for a club that have had 30 years of nothing and that supposedly is in a hurry. We also have a DOF model that is now supposedly seen to work so if it does, it should mitigate against at least some aspects of more change.
But, when all is said and done I hope 110% he is considered to be doing enough to stay here beyond this season, and several more to come.
