are the players over priced?

I just got promoted to league 6 and my players on average are 4 star and 5 star and worth 3 - 4m but if I want to buy a player of the same age who is 4 star the game is asking 7 - 10m this cant be right

example

my striker aged 18 quality 45 5 star no special ability value 4.8m

striker I wish to buy

striker aged 20 quality 47 5 star no special ability value 7.9m


goal keeper I want to buy

aged 18 quality 44 no special ability 4 star value 11.5m

keeper I own

age 19 quality 48 no special ability 5 star value 5.6m

They are fast trainers. Fast trainers are young player who are overpriced and have better training progress than the players normally do...
