Serbian Super League new rules

New Serbian League system now says that the playing squad has to have two U-21 players, 2 of U-21 players must be on field at every minute of the game..

Only players that have Serbian nationality are U-21, second nationality also counts.

I’ll see what I can do, I aren’t sure the game has a rule for them being in the pitch at all times but it should be possible to have a squad rule for two u21 Serb players in every starting line up.
