I got one NGE youths for my LVL-2 team.
Here's the info:
age - 19
value - 2.17M
quality - 28 (5*)
position - ST
gain - 21/86/92
I found out this, Not every Nord Gen are the fast trainer IMO.
And some players gain more in a specific training type, some gain more in Cardio & some in Practice Match.
I am still not sure for every thing.
I will research more but I think there's a lot of experienced managers already found out.
So... please share your experiences.
