Very fun game There are a few things I would like to see improved.
About job offer
It's a shame that when you receive an offer from another club, the only option is to take the job immediately.
I would like to see the option of "I'll take charge next season.
I would like to see an option like "I'll take charge next season" or "I'll take charge in the winter".
About Rental
I would like to have options such as purchase option or loan term extension.
About the growth of players
The growth of young players (even 22 year old players) stops. It's a pity that when a player reaches the minimum of his estimated potential, he doesn't grow any further, even if he is a growing player who regularly plays in games.
Status of other clubs
As the season progresses, other clubs often do not reinforce their replacements after their main players retire, and continue to use less capable reserve players (even big clubs like Juventus and Real Madrid). It would be strange if the clubs that don't operate don't have players promoted from the youth academies. Goalkeepers, in particular, are not reinforced when they retire, and many teams will have only one goalkeeper in their club.
