@slavishen I guess there were such rare cases, but the strength of the football/basketball/any sport league back in the days of Yugoslavia was due to huge, local fan base. Clubs such as Radnicki Nis or Hajduk Split were successful because they had local support. Football fans today are like NBA basketball players. You see top basketball stars joining forces together to win the championship, but in the 90’s it was much greater rivalry and it could never happen. The same is in football with the football fans. Basically everyone cheer for top teams. That’s why smaller clubs disappear gradually. I can say today football is not even so popular as back then, perhaps I’m just talking about Serbia but there isn’t hype around derby matches.
