If we lose Chiellini there is no point to blame only Secco, only Ranieri, only Davide Lippi or only Chiellini. It is probably everyones fault.
If the problem is money then i blame Chiellini more than the management. He didn't prove himself enough so we can offer him an improved multi million contract. We can't offer him big money, not now when every penny is important. After blackmailing, we did offer improved contracts to our stars. If we do that with Chiellini then nothing will stop Zanetti, Zebina and Marchionni to do the same. We just can't afford it now when we still struggle with money needed for another defender and the big bucks we'll need next year for Nedved's replacement.
Giorgio should be smarter than this. He knows he's good, he knows he'll make tons of money in his career and he knows he'll be given a better contract if we make it to champions league next year, even better than what he'll earn in ManCity. He should wait one more year instead of rushing with his decission.
If the problem is playing time then i blame Chiellini and Ranieri the same. Ranieri for being blind and not able to see Chiellini is better option than what we have in defense and i blame Giorgio for being a cry baby. If he thinks he's better than Molinaro then he will have to prove it. After the friendlies or after the first rounds of serie A , Ranieri will have nothing else to do but admit Chiellini is the best one we have. Chiellini is rushing again
If the problem are money for the club then it's the management that should take most of the blame because we can find another way to get 10 million euro. Sell Blasi, Zala and another not needed player and there you have the money.
But the real reason must be a sum of all 3 reasons i mentioned. Chiellini wants more money and more playing time that the board and Ranieri don't want to give, and the board wouldn't mind getting 10 million euros even if they have to lose Chiellini.
They are all guilty.
