Is a power trained player worth it?

[nikolgiorgos]

so you recommend me to use a player from my academy instead of a young 20-21 aged scout? I mean that scout is already pre equipped with a SA and also 6 close to 7 star rated...

yes, the "good" years of a fast trainer are 18-21.
So if you buy a recommended 20-21 y.o., you already lost two.
