Sure, he went from being 10* shit to be 9* shit, that's an improvement.
I don't hate him, as others in here do, i love his passion! But i am a realist too. Considering the CB's we have in rank, and that we are slowly shifting over to a back four.. Plus the probability of getting Rugani Next season. Someone has to leave... Barzagli is old and injury prone so he will most probably see out his contract here, and work as a mentor for the others. Chiellini is 29, so if he signs on, one of the spots will be his, or his to loose. So out of Ogbonna,bon bon and Careers, at least one has to go.. Bon Bon is gonna bring in most cacs, so why not...
Let's reconsider from my POV:
First of all, like u already said, barzagli getting old and, injury prone.
Second, quality of defender nowadays is pretty much sh*tty, and expensive too, look at David Luiz, 40 mil for David Luiz, if u want better defender, u need a huge crapload of money, which sadly we don't have currently. I don't believe rugani will make sudden impact, so I put my faith in Bonucci.
Third, he already become azzurri captain in relative young age, that must count something. I believe he's form will affected greatly by that newfound confidence. And this season he is one of our top performer.
Fourth, I believe, when time come to release one of our defender, Ogbonna is the most likely. Sure this only my opinion, but it seems likely.
Fifth, we're already lack of DC, why we need to release one immidiately? That if u consider Cecares as RB, which is he superb at.
