shaky start, i agree. but was it like 2 games? maybe 3? (and let's not consider the unlucky handballs, especially not the one vs lecce, which shouldn't have been a penalty at first place)
what i'm saying is that chiellini's absence wasn't that big of an issue. conceding 1 goal per matches isn't what you call juve worthy, and it was down to systematic problems like midfield providing zero cover for the cb's, our fullbacks getting cancelled with crosses and through balls, and also the zonal marking with dead ball situations took some time to get used to. also, buffon saved our ass in the coppa final, and it only was napoli, a one trick pony team parking the bus and countering when it was possible.
anyway, i agree that at the moment, attack and game management needs more attention than defending. we've been more solid than not at the back lately.
