AC Milan is like many Italian clubs in the last few years. They don't have too much money like clubs from Premier League or La Liga. They have to look at free players to convince those players participate in their clubs. Inter Milan, AC Milan, Roma, Juventus focus on this approach and they got some success. They aim at young players, not old players if they have to spend money for transfers. Because they want to build a squad that can play in a next 5 years or longer with those players.
That's right, few season before Berlusconi era ended, AC Milan has experienced financial problem already, several transfers of ownership have not been able to help improve AC Milan's finances to date. The failure to sell important players in the last few seasons has increasingly made AC Milan have minimal income from player sales. Currently, Milan may only be able to buy players at low prices, or try to bring in players on loan. Milan need to sell players the club doesn't really need. The best solutions for know is to start leveraging talent from the Primavera. This is an important time to improve AC Milan's finances again.
