Chelsea ended Fluminense’s run in the 2025 FIFA Club World Cup with a 2–0 victory in Tuesday’s semifinal at MetLife Stadium in New Jersey, eliminating the Brazilian side from its bid for a first global crown. The loss quickly reverberated in Rio de Janeiro’s intense football rivalries. Fluminense had taunted Flamengo and Botafogo last week after both clubs crashed out in the round of 16, asking them about the “climate” back home. Within minutes of the semifinal defeat, the two rivals returned the jab online. Flamengo posted a screenshot showing a mild 21°C in the Laranjeiras district, echoing Fluminense’s earlier tweet, and added a lyric used by its supporters — “No Rio não tem outro igual” — underscoring that it remains the city’s only world champion after its 1981 title. Botafogo followed with the caption “FRI8”, a play on the Portuguese word for cold and the club’s eight consecutive wins in recent derbies, alongside an image of Chelsea midfielder Cole Palmer, nicknamed “Cold”.
