AC Milan has seen a shortage in the striker position, last season they brought in Mandzukic (unfortunately not effective), this season they brought in Giroud, it's true that Milan need young players, but it seems Milan's financial problems are preventing them from buying talented young players who certainly have a higher price. Maldini & Pellegri are the names of the young strikers who are at Milan atm, but for now it still takes time for them to become great players.
Mandzukic is great striker and he can play in many positions but he is old. After Mandzukic, Giroud is another player to keep the transfer strategy of AC Milan. They try to use old players with cheap transfer fee if they can and they want to combine old players with young players. I think it is a good strategy because after a few successful seasons, young players will grow up and they will have better finance. Then they can change their strategy and buy star players with higher transfer fee.
Serie A is a place where older players are needed, even though they have young players who have good potential for the future but in the end they will either let them go or sell them when there is an offer.
Because Serie A now are not the best league in the Europe and clubs there have less budget for transfers like 20 or 30 years ago when Serie A
clubs dominate the Europe.
I think Mourinho works best with this kind of team, solid teamwork, without popular star players = no drama.
The last two teams he coached just had too much ego, this one I think will work.
Mourinho still works very well but I hope that he won't create conflict of interests with director board and players. If he can do so, he will succeed in Roma because Serie A is perfect for coaches who like and focuses on tactic like Mourinho.
