In a tense atmosphere after Red Star Belgrade's dominant 5-0 victory over Novi Pazar, the Delije fan group made headlines by threatening Croatian fan factions, particularly Torcida and Tornado. This threat comes in the wake of a reported failed attack by around 40 masked hooligans targeting Croatian fans who were attending a game in Vienna. Regional media has highlighted these threats, indicating that tensions between Serbian and Croatian football fans have escalated significantly.

The Delije unveiled a message at their game that warned of their impending presence in Vienna, suggesting possible retaliation against Torcida for a recent incident. The ominous message included declarations that their 'shadows would walk in Vienna' and instigated fear by mentioning intentions to threaten rival fans. This signal not only reflects the intense rivalries in the Balkans, particularly in football culture, but also illustrates the increasing violence among fan groups in the region.

The unfolding situation presents concerning implications for fan safety and the broader sporting environment in the region as incidents of violence among rival fan groups continue to pose challenges. Both local authorities and fan organizations may need to take preventive measures to address the potential for violence at sporting events and protect the safety of all attendees within these environments, which is increasingly becoming a topic of discussion in regional sports media.
