value increase after training

[dominus]

Hey guys I was wondering how much is the value increase when training young players?
In particular if I buy for example a 3 star 18-19 years old player for 2 millions and train him up to 5 stars how much will he cost then? Is it worth it as a money making strategy?

depend on League and Quallity of player
i calculate by
mkt price / (defensive score + offensive score + moral score) = price per score
if the player who well growth the price per score about 0.38 (this score active in League14)
PL" every turn up league the score will +0.02
