The most expensive now are around 3.5 - 4M but they are 37-39 quality (40 is scout on my level {4} ) and 21 T seems to much to me , he is 31Q now 4*, till the end of the season i guess he wont get 35 (where he will get +1 star , making him 5*), and at the beginning of the next season he"ll be 3*,maybe i""ll release him , but not sure yet.
