No trainer is fast forever

[Tactician]

Yeh, that sounds about right.
Coupled with the slowdown as they increase in quality It's why I can never understand when i see people training older players to 7 or 8*, must take a crazy amount of greens, even if the guy was bought as a Scout

Who would powertrain players bought from the scout list, hahaha. They are so slow to progress, even the most expensive and younger ones. Scout players are players that are expected to have reached their peak or nearing their peak, and they can be a 1 or at most 2 full season players unless the manager deliberately wants his team quality to drop to the 80% or below.
