This business model would make perfect sense if the club would just sit down, decide an identity which to follow on the pitch and integrate as many academy players as possible whilst making good business by getting bargains and selling loanees. Right they have no patience for the manager to develop a squad which forces the manager to ignore the youth and there's still after all these years no clear identity of play. The lack of vision is even more apparent when you look at who have been proposed as the successors of Conte. Allegri, Enrique, Simeone are all completely different managers with different philosophies.
I think it all starts with the identity. A clear philosophy from the youth teams to the first team squad would make the transition a lot easier for the academy graduates. Look at City, Pep can just throw kids in the starting XI and they can perform as well because the philosophy is so clear and everyone knows what to do. Recruiting new players also becomes easier when you exactly what type of players the squad needs. For example, buying Morata (ball-playing forward) and Bakayoko (the opposite of a technical midfielder) in the same transfer window makes no sense at all.
