The issue with the FC 25 Coins method is that it makes the gamer feel largely irrelevant to their players' development. Moreover, a particular player having a great season and getting a significant rating increase used to be one of the most rewarding aspects of the older games, and it encouraged gamers to buy young players that they felt they could get the most out of. On the flip side, a player could have an excellent season but stay on the same rating because of a predetermined ceiling placed on them, which is frustrating.
FC 25. like a handful of its predecessors, lets managers assign scouts to various countries around the world and sign talented young players to their youth team. These players will sit in a menu, waiting for the manager to either promote them to the first team or release them. To make this decision, the manager can see each player's current ability and an estimation of their stats and potential.
To put it bluntly, this feature is just as unengaging as it sounds. Instead, it would be great if Under 21 teams were added. The manager could have the option to play as this team, which would let them try the players for themselves and make a decision on their FC 25 Ultimate Teamure based on actual gameplay. If this was combined with the aforementioned performance-based growth feature, it could make for some exciting times if the manager finds a player that they feel would work well for their team and playstyle.
Aside from a few key details like goals and assists, cheap Fut Coins games have always had a notoriously minimal amount of stats and analysis for managers to judge their players on. Recent games have improved on this, to be fair, most notably with additions like XG (expected goals) and each player's average position throughout a match.
