Boca Juniors host Vasco da Gama in the first leg of their Copa Sudamericana semifinal on October 14, 2026. The match takes place at Estadio Alberto José Armando in Buenos Aires, with Boca looking to take an advantage into next week’s return leg in Brazil. The hosts have gone 17 matches without defeat and won their last five home games, but Vasco arrive unbeaten in their own last five fixtures. With both sides in strong form, the opening leg offers Boca a chance to make home advantage count against visitors who have been difficult to beat.

Boca Juniors' Recent Form and Key Stats

Boca Juniors extended their unbeaten run with a 2-2 draw against Instituto on October 9. Across their last five matches, they have recorded three wins and two draws, scoring an average of 2.2 goals and conceding 1.0 per game. Their Copa Sudamericana record stands at four wins, one draw and one defeat, with averages of 1.7 goals scored and 0.5 conceded. That combination of recent results and a strong defensive record in the competition gives the hosts a solid platform for the first leg.

Boca’s route to the semifinals included a tie against San Pablo. A 1-0 win in the first meeting proved decisive when the return match ended 1-1. The side has also won its only two previous international competition meetings with Vasco da Gama, by 3-0 and 1-0. Those results add context to this fixture, although Boca’s more immediate source of confidence is their run of five successive home victories.

There is a significant personnel setback for the hosts. Leandro Paredes came on against Instituto but left the field after less than 15 minutes because of a physical problem. A muscular injury is expected to keep him out for three to five weeks, ruling him out of this match. His absence leaves Boca with an adjustment to make as they try to carry their unbeaten form into the semifinal.

Vasco da Gama's Recent Form and Key Stats

Vasco da Gama also come into the tie with encouraging results. They drew 0-0 with Remo on October 10 and have won four of their last five matches, drawing the other. Over that five-game stretch, Vasco have averaged 2.2 goals scored and just 0.4 conceded. In this Copa Sudamericana campaign, their record is six wins, four draws and two defeats, with averages of 1.6 goals for and 0.8 against. The competition ranking supplied for this match places Vasco first and Boca second.

The visitors have improved their domestic position after taking three wins and a draw from four league games, a sequence that moved them out of the relegation zone and left them 14th. Their continental progress has followed a recurring pattern: against Olimpia, Independiente Santa Fe and Independiente Medellín, Vasco drew one match and won the other. They did not, however, win away from home in two of those three ties, making the trip to Boca an important test of their recent momentum.

Facundo Colidio cannot be registered for Vasco in this competition after having been among River Plate’s selected players before his transfer during a knockout tie. Spinelli, credited with seven goals in 36 appearances, is therefore set to retain his place. Alan Lescano and Santiago Sosa have also entered the selection picture since arriving in midyear, while Marino Hinestroza has yet to record a goal or assist in this season’s international campaign.

Boca Juniors vs Vasco da Gama Match Analysis

This semifinal brings together two teams whose recent results offer little sign of vulnerability. Boca’s 17-match unbeaten run and five straight home wins make their venue a clear advantage, while Vasco’s four wins in five games and low recent goals-conceded average show why they cannot be dismissed. Boca have won both previous international meetings, but Vasco’s current form suggests the hosts will have to work for any first-leg lead.

The visitors’ first-half numbers point to the possibility of a measured opening. At least one team has failed to score before half-time in 37 of Vasco’s last 39 matches, while fewer than two first-half goals have been scored in 20 of their last 22 games and 18 of their last 20 away matches. Their latest 0-0 draw with Remo is another reminder that recent attacking averages do not guarantee an early breakthrough.

For Boca, the challenge is to turn their home record into an advantage without Paredes. Their narrow first-leg victory over San Pablo shows how useful even a single-goal lead can be across a two-match tie. Vasco have repeatedly advanced by pairing a draw with a win, so a close contest would still leave plenty to settle in Brazil. On the evidence available, Boca’s home winning streak and unbeaten run give them the stronger case for an opening-leg victory, despite the visitors’ impressive recent form.
