Can't wait to trying it out, you can have 4 players 18 y.o at the begining of the season for free, you can spend or train them on the following season, looks like a good idea, the improved training really seems expensive but if you consider it so do the majority of premium players sold during the season.

The only really bad thing i see about it is that you invest and then loose against a tanker team, for me its reason enough not to invest.
