- Barzagli's level decreased drastically, and this is an ongoing process. Now his presence in the list is rather nominal.
- Benedict is twice as good as Caceres when they are both fit.
- Benatia was basically on the same level as Bonucci as a defender, but without psychological issues of the latter, which often surface when the pressure is high and which is not a good thing to have if you're a contender for a CL title.
But even with that, last year's result was far from what this team want to achieve this season. So it seems like an obvious downgrade or, at least, a stagnation with a strong negative trend.
The only positive thing that can be said about CBs is that Chiellini seems to have risen his level even higher this season, to the GOATs level for defenders. But he still has that tradition to watch games injured from the stands when his presence on the pitch is highly needed, so even his legend-level status doesn't really make you confident in defensive options of this team on the distance of at least several months.
