16th, 15th, relegated. Not what I'd call good after an extended time to actually shape the side. It indicates to me that he was incapable of improving a defence.
Right but the point is it took him 4 years.
You're arguing we need to sack him to keep us up this year, as if the moment we start dropping down the table, he'll panic and not cope. That didn't happen, in 3 out of 4 relegation fights he had enough to keep them up despite his team being in awful form coming into spring. He is comfortable in those situations, it's his backyard.
Now I don't think we'll seriously be in one this season but if we are, Roberto seems like he's the streetwise guy who can get us out of it as much as the likes of pulis or others.
