How can i train my players to reach their potential faster? Is there any other way except the basic training?

Mostly player's are promoted from Youth academy to early and this kills taleni , but it's a good way to make money if you want to sell but if you want the player to how well leave the player for 3 seasons in the acai promote him when he's 21/22 years or even 23 you will find that his rating is 78 potential 85 this saves you slot of time and job trying to train a player , that's why there is a youth academy

Thank you for your reply! I promote players late, 23 or 24, but even then, they lag behind their “progression” despite playing them in every league game until they are tired and training every day. Am I missing something?
