An executive from Football Supporters Europe says concerns are increasing about potential violence at World Cup matches, citing what he describes as problems with ticketing and fan segregation. Ronan Evain argues FIFA has not put adequate measures in place to keep rival supporters apart, saying this increases risk for fans inside stadiums. Multiple rival-supporter incidents are referenced in reporting, including a brawl involving Iran fans in the stands, which is presented as an example of wider safety concerns. Evain also claims FIFA has “lost control” of ticket arrangements, arguing that oversight has contributed to difficulties in managing crowd movements and preventing clashes. The reporting frames the issue as one of stadium security and matchday management, focusing on how tickets and segregation policies affect where supporters sit and how they enter venues. No specific new policy changes by FIFA are described in the available summaries, but the comments are presented as a warning that existing arrangements may leave fans exposed to rival-group contact.
