For Bastia, I understand
I haven't played with them on the last 2 opus (Before N3).
But for the historic Nancy team in youth training (Platini, Lenglet, and other) it is difficult to understand that even in U18 R1 there is a lack of U19 players.
Ok for the grey player I didn't know because I always play with clubs that have a lot of U18-19 (Nancy, Barcelona, Man City, Sochaux, VAFC)
This is not a problem in itself for playing but for fans of the club and the game it can be disappointing
