Club Social y Deportivo Defensa y Justicia is an Argentine professional football club from the Florencio Varela district in Greater Buenos Aires, competing in the Argentine Primera División. Founded in 1935, the team plays at the Estadio Norberto "Tito" Tomaghello. Their colors are yellow and green. Under the presidency of José Lemme and the influential guidance of coach Julio Vaccari and his predecessors, Defensa y Justicia has undergone a stunning transformation in recent years. Historically a modest club, "El Halcón" (The Hawk) soared to unprecedented heights by winning its first major international trophy, the 2020 Copa Sudamericana, followed by the 2021 Recopa Sudamericana. This golden era, built on a cohesive style of intense pressing and collective play rather than star names, has cemented their reputation as one of South America's best-run clubs. They continue to be a force in both domestic and continental competitions, consistently developing talent. The club's identity is deeply rooted in its community, with a loyal and growing fan base. Defensa y Justicia is the modern blueprint for a successful, sustainable football project in Argentina.
