For me, the most important football club is my favorite: FC RED STAR / FK CRVENA ZVEZDA - European Cup Winner in 1991 and Club World Champion the same year!
Our stadium (called "Pequeno Maracanã") has received over 100,000 spectators in the past. Now, the capacity is reduced to 55 thousand seats. Unbelievable atmosphere during home games, and great support in away games, means that the club has fans spread all over the world!
Here is the great support during the match CL vs Liverpool (2: 0) in the season in which they won the Champions League:
