The underlying problem, that e.g. star potential players are not seen as worthwhile trainees (with Manon the notable exception) is in my opinion the training system. Make it slightly faster and more flexible with e.g. increased efficiency for 3 position training for a total of 9 players and those players will get more training.
Star players have not been worthwhile in the past, only with the FAs gone and the global talent level declining they become valid options to train. It can still be debated wheter those players are useful on a DIV I-II level at all.
Any additional influx of money into the BB economy is bad (promotion bonus).
This could be the biggest problem long term, I think transfers north of 10mil, might become the standard in a few seasons.
