Relax people , what are the odds that all of Chiellini , Barzagli and Caceres will be all injured in the same time during the whole season? Sure , anything can happen but obviously here is not the case and we should relax about the CB position , even for the most panic moments we could call up someone as Filipo Romagna from the primavera and i think we will be fine.
Given the discussions on Astori , i see most are against it , even it happens it is a ok move , he would be like the 4th choice even with 2 defenders injured so he is just a panic option , no need to credit him or not because as i sayd earlyer there are 1:100000000 odds that we will have 3 CB's injured long term in the same time.
