Greek Super Cup

I am really annoyed that Greek Super Cup game is played on September 5. That's one of the World Cup/EURO Qualifier days. So, all my international players are joining there national squad while my youth/reserve players are playing in GSC? I think Super Cup should be a nice fight between two best teams in country, in Greece between rivals Olympiakos and Panathinaikos. But is the game interesting if my keeper, 2 defenders, both wingers and both forwards ain't there? The best team suffers, because good players = international players. I have to play without Belluschi, Dentinho, Razack Traore, Sifakis, Vidal... while Panathinakos are playing with players that are a bit too bad for national team, but still better than my youth players (because most of my subs are called up too a.e. Laczko, Sikov, Nikopolidis...) This is not a Super Cup it's kinda friendly.
