No club may have more than 25 players on List A during the season. As a minimum, eight places are reserved exclusively for "locally trained players" and no club may have more than four "association-trained players" listed in these eight places on List A. List A must specify the players who qualify as being "locally trained", as well as whether they are "club-trained" or "association-trained".
Perhaps I'm not understanding it correctly, but I assumed it was max 4 association trained and as many club trained as you want.
Did I get it wrong?
