'Maybe the young players could reflect the team and come out with the squad average quality ?'

Do you think that this can happen, especially from what seems to be greedy company like Nordeus?

Some things will likely never happen in this game because it won't benefit the company financially. Nordeus seems to prefer that you either you spend 15-28T or so on a 4 star player or release it to the market where other players will bid and fight against each other for him.

There are so many things that can be improved in this game, but some things seem that they will never happen, at least not in the user-desired way.
