Portuguese League System registration

[un_noob_666]

Hello.

I have a question regarding the Portuguese league system.

I don't understand what the first-year senior player clause is nor how it works. When I register youngsters from my academy who follows the 2001-2003 years, this does not change.

The league considers it ok at the moment because I registered less than 33 players, but if I try to register one new player, it shows it as red and does not let me register any other player.

I don't understand how it works.
