but you don't change it, in fighting for top talents to make this prices even higher ;)(and yes you are not the only one who does it)
I believe for training it makes more sense to bring up some 100k trainees, to a 1million deal then paying for potential stars the sum you pay for already stars. Or get a already star, and train him out of position to make him to a kind of star player who had a higher value(and be happy that you don't have to train that much, as you had to do with a youngster).
