Key factThe first leg ended 0:1 at La Bombonera on 13 October: Adson scored in the first half and Vasco held on after Gómez was sent off. Since then Vasco lost 0:1 at São Paulo in the league on Sunday, and Boca beat Talleres 2:1 on Saturday. Over their last ten games Vasco are 6-2-2 with 14 goals scored and only 4 conceded: six clean sheets, both teams scored in just two of those games and only three went over 2.5 goals. Boca are 6-3-1 over ten with 19 scored and 10 conceded, and both teams scored in six of them. In the Brasileirão Vasco are only 15th with 35 points from 30 games (ESPN), so this cup is their main target of the season.

Vasco vs Boca team news

Vasco without Andrés Gómez; Paredes the big question for Boca.

Vasco
  • OutAndrés GómezSuspended
Boca
  • DoubtLeandro ParedesSources differ
  • DoubtAlan VelascoReported injured, not confirmed
  • DoubtTomás BelmonteMissed the first leg, status not confirmed
TacticsAndrés Gómez is suspended after his two yellow cards in the first leg (Lance, Gazeta Esportiva); Lance names David or Marino as his replacement. Lance also reports that Facundo Colidio is not registered for the Sudamericana, while Gazeta Esportiva puts him in its predicted XI, so that point is not settled. Gazeta's expected Vasco side: Léo Jardim; Paulo Henrique, Saldivia, Robert Renan, Cuiabano; Santiago Sosa, Tchê Tchê, Alan Lescano; Adson and Bruno Duarte up front. For Boca, Leandro Paredes is the key doubt after his thigh injury on 9 October: Río Negro writes that Rodolfo Arruabarrena sees a risk and will decide before the game, while Bolavip and Diario Panorama say he came through training and is likely to play. Tomás Belmonte missed the first leg and Alan Velasco is coming back from a muscle tear, with Sebastián Villa ahead of him (Mamba Sport). Río Negro's expected Boca XI: Montero; Lozano, Di Lollo, Facundo Herrera, Blanco; Ascacíbar, Paredes or Battaglia, Delgado; Velasco or Villa, Merentiel, Leonel Flores. Jesús Valenzuela of Venezuela referees, with Juan Soto on VAR.

SourcePick
SportsGamblerBoca 0:1 and under 2.5 goals
Our positionSportsGambler and we agree on few goals and disagree on the winner of the night. A 0:1 would take the tie to penalties; we think Vasco score at least once on the break at a full Maracanã and go through.
No. 07 · Scenario & score

Vasco vs Boca predicted score

Boca must attack, Vasco wait for the counter.

A draw in normal time sends Vasco to the final; a Boca win by one goal means penalties, and by two goals Boca go through (Gazeta Esportiva, Misiones Online). That forces Boca forward from the first minute, while Pedro Emanuel's Vasco can give up the ball and look for Adson on the counter, in front of a sold-out Maracanã of about 70,000. Over their last five games Vasco allowed only 2.0 shots on target per match. 1:1 is our main score; 0:1 and penalties is the alternative. Under 2.5 goals wins with 0:0, 1:0, 0:1, 1:1, 2:0 or 0:2 and loses with 2:1, 1:2 or any score with three goals or more.

Under 2.5 goals: why this pick wins

Why we back it

Vasco have conceded four goals in ten games and kept six clean sheets, and only three of those games went over 2.5 goals. Winning the first leg 1:0 with ten men showed that Pedro Emanuel's side can protect a lead. Boca need two goals to go through, and we expect them to score one at most. Our score is 1:1 and Vasco in the final, and under 2.5 goals also holds with 0:1 and penalties.

No. 09 · Arguing against ourselves

What could beat our pick?

Why there could be more goals.

  1. Boca scored 19 goals in their last ten games, and both teams scored in six of them.
  2. A full Maracanã could push Vasco to attack rather than protect the lead.
  3. If Boca go 1:0 up after the hour, both sides have to chase, and 2:1 or 1:2 become real.

FAQ

What does Analysis mean?

Our full analysis of the match and the result we expect, without a bet.

How do you choose a pick?

We start from the market, then check a statistical model, named previews and our own scenario test against everything that moves the result: lineups, rest, motivation, style and team news. We publish when at least three of the four agree and the pick wins in the main scorelines. A warning sign, such as a back-up goalie or tired legs, moves us to a safer market or leaves the match as analysis only.

Can a prediction change after publishing?

No. The pick, odds and time are locked when published. Updates go into the log above.
