Several brothers compete at the World Cup for different national teams, with both outlets reporting seven sibling pairs in total. The story highlights that, rather than playing on the same side, brothers are split across teams, creating sibling rivalries at the tournament. While the outlets focus on the overall number of such pairs, they do not provide additional details in the supplied text about which countries the brothers represent, their positions, or match outcomes. The key point shared across the reports is the presence of multiple brother pairs facing off in international competition despite family ties. With seven pairs involved, the tournament includes a notable instance of mixed family allegiance, illustrating how international selection can lead to siblings wearing different national colours. The reports present this as a feature of the tournament rather than an incident, emphasizing the novelty of sibling matchups rather than controversy or specific games.
