You are right. Since Milan doesn't have a lot of money right now, they should try to sign young players. If the coach is experienced, it is possible to perform well with young players. Milan aim to bring stability to the performance. This team will not fight for the title. And therefore Milan management has no interest in spending too much money. However, there are likely to be several major changes to Milan's squad next season.
So far, Milan has performed well last season until it qualified for the semifinals of the UCL even though it was finally defeated by Intermilan, but Milan has good quality players, even though they don't have the money to buy great players and are famous for the current players, it seems like enough for Milan to be able to compete in the league. next season with existing players or youth players.
I'm not a Milan supporter but so far they've played well with the existing players, consistency and discipline have made them play well as a solid team, but if you want to buy a player, young players are better because many clubs recruit young players because of course during the season the future will be very tight.
Milan's squad is not that weak. But they do not have a strong squad to win the title. Milan has a number of talented players in their squad and their match tactics are good. This squad is capable of playing well as a team. Because of this, they can be in the top four of Serie A. However, if Milan wants to compete for the title, Milan definitely needs a stronger squad. Since they don't have enough money, I think it is useful for them to form a youth-based group. Even by selling young players as they become experienced, Milan can make money in the future.
