The world's most passionate supporters
4. Red Star Belgrade
Any supporter base with links to paramilitary organisations is always going to create a formidable atmosphere. In the 1990s, Red Star Belgrade's intimidating Delije, the fanatical supporters in the north stand, were led by the notorious paramilitary leader Zeljko Raznatovic (known as Arkan). The incredibly violent riot between Delije and Dinamo Zagreb fans in May 1990 was seen by some as the first sign that the war was about to begin. Thankfully, it is not just their connection with a dark chapter in the region's history that the Red Star fans are known for. In 1991 they had their greatest chance to shine when the club went on to win the European Cup. Delije and the rest of the Red Star supporters regularly fill the stadium, particularly the north stand, with a flood of flares that creates an intensely hostile environment for opposition teams and fans.
