Massive difference in player costs in auction

[Gert Funck]

Why

a 18 yr old rating 34 is of 1.66M No skills ; MC
a 19 yr old rating 33 is of 4.14M No skills ;MC

Question:- why such a huge price difference when moreover 18yr old is better starred why is there so much difference any clues anyone ??

the more expensive is a faster trainer, that is the answer
