I see, a few more guys told me the same.
The ones that I have in mind right now are:
AMR - 124% (current) - 18yo
DC - 122% - 18yo
AML - 124% - 19yo.
I also have in mind other players of my squad for the future:
DC - 122% - 21yo
DR & DL - 113% and 114% - 20yo both.
ST - 130% - 20yo.
According to the guide of fast trainers, they all are. But my goal right now are the first 3.
