Some really great info guys!
Thanks Buffs for the detailed numbers, and sharing your One Season Wonder.. I got one of those old guys on one of my teams, he's 32 I think and he'll be a Two Season Wonder since he hit 6* this season..
But he has no resale value, and so I have to save up to replace him.. as he's an attacking winger finding a replacement isn't easy, so I am happy I have another season to look.
The young newly generated players are the fastest training, but the "hot prospects" can be a good deal if you find one with their attributes added as you like, because the generated ones are all fairly even, with maybe a point difference. So if I see a 21 who's really expensive I'll look at his skills to see if I want him.
