the requirement for players to go to academy it has to be 20+ and have contract more than a year. since the player i want to send to academy initially on his last year contract i have to extend his contract 1st so that do use cash. which i dont care losing.
also there're free coach that's consume 13days now, just enough to get your player back at final week and if you do have 28players probably will have it unsigned back.
i dont think they will gives out coaches on final week that'll have players out til next season because that'll break the game, like you and others think bout, something that can manipulate your team % without the players academy
