I agree, but I think it's the least likely case. I obviously wouldn't put it past them, but IMO they're keeping him because, like it or not, they're seeing something in him worth hanging onto.
Whether the magic of those 10 matches still persists, or they're getting the impression from the amount of goals we scored this season that we will be fine as soon as Romero and VdV are back (and maybe after we sign a defender or two), or his captivating aura as an ideologue clouds their judgment and leads to them being less result-oriented in their evaluation of him compared to how they evaluated previous managers, or any combination of those, it seems they'll continue being very patient with him.
Is this a gross misjudgment? Possibly. Is it just lack of ambition? No.
This patience is of course not unlimited, but they may not run out of it as quickly as some people here hope. Because of the reasons outlined above
