Its 100% clear that Blanc, who is the boss by virtue of being the frigging President, is the one who chose Zac, endorsed him. Bettega didnt want him, and was after Gentile and others. Secco does not even have anything to do with this. Since Bettega became our GM, he even has less responsbilities with transfers, is more of Bettega's wingman.
Blanc is the one that makes the decisions, that should be very obvious by now.
