Playing 48 minutes is not officially supported by the game
The managers in this game are just that - managers - not coaches. Coaches do have a bit of free will...
I cannot say if that was done intentionally to prevent making 48 minute per player per match training reliable, but it does add a little bit of reality
This whole training system is not realistic
Currently we do not support it, intentionally, but that's not set in stone.
In the end, we decided that only things that affect the game in the extreme deserve such an approach.
The loss is felt by all, because of the lost realism.
Such concentrated training is fastest (per specific player), and is the best way of training potential NT players which are a highly sought merchandise.Therefore, such training involves some risk, but with potential high reward.
