In the opening leg of the Copa Sudamericana semifinals, Vasco da Gama secured a 1‑0 victory over Boca Juniors at La Bombonera, giving the Brazilian side a first‑leg advantage in the boca vs vasco tie. The result silenced the home crowd and set the stage for a decisive return match in Rio de Janeiro.
boca vs vasco semifinal overview
The encounter marks the start of the decisive phase of South America’s club tournaments, running alongside Libertadores semifinals that feature three Brazilian clubs. Argentina’s recent dominance in the Sudamericana—11 titles overall—adds extra pressure on Boca to restore national pride.
boca's lineup and injuries
Coach Rodolfo Arruabarrena will start without captain and midfielder Leandro Paredes, who is out with a right hamstring tear. Boca relies heavily on striker Miguel Merentiel, who has netted 13 goals this season in league, cup and continental play. The team also continues its domestic campaign, sitting third in the Clausura with 21 points.
vasco da gama's path to the semifinals
Vasco reached this stage after dispatching Independiente Medellín, Olimpia and Santa Fe. Managed by Portuguese coach Pedro Emanuel, the side balances its Sudamericana run with a domestic league campaign that finds them 14th with 35 points, just three clear of the relegation zone. Forward Facundo Colidio is unavailable because he was registered by River Plate for the knockout phase, leaving Adson—who has four goals and three assists—to lead the attack.
historical context of the rivalry
The clash revives a classic Argentine‑Brazilian showdown that has been dormant for nearly a month due to international fixtures. While Brazil currently leads the overall South American title count 25‑25 with Argentina, Argentine clubs have won the last two Sudamericana editions (Lanús, Racing Club). Boca seeks its first international trophy since the 2007 Libertadores win.
what to watch in the second leg
With Vasco holding a slim advantage, the return match in Rio will likely be decisive. Boca will aim to overturn the deficit, leveraging Merentiel’s scoring form and home support at La Bombonera in the first leg. Vasco will try to protect the lead while navigating a tight domestic race, as a slip could threaten their league standing.
Both clubs also compete in other domestic competitions—Boca in the Copa Argentina and Vasco in the Brasileirão—adding depth to their squads and influencing player rotation for the semifinal.
