I'm getting gotze and want to improve his finishing however, I don't want to slow his other attributes rise. How do I know if a player is progressing fast, slowly or good enough in training? Is it through Assistant Manager's training report?
You can refer to your Assistant Coach Monthly report progress on players, or you can track them based on the 'Training' tab in the player's option. The tab is useful for you as it can give you the feedback from all the coaches to you on the player's progress and allows you to see the improvements that your players have made.
