As I stated, the player must be trained for 3 years by the time they reach their 21st birthday (and must be trained for that period in the same country as your own team if loaned out).
wait, wait, wait...
do I understand that right:
If i have 17 year old Brazilian (in Belgium), I get him homegrown in 2 ways:
1. train him in my club for 3 years
2. loan him to any club in my country for that period (3 years).
Do you mean homegrown also as club-grown?
