Updated September 14, 2026. São Paulo go into the second leg against Boca Juniors with a straightforward scoreboard equation and one major absence in attack. After losing 1–0 at La Bombonera, Tricolor need to win by two or more goals to advance directly to the CONMEBOL Sudamericana semifinals. If they win by exactly one goal, the aggregate score will be level and the tie will be decided on penalties. A draw or a defeat sends Boca through.
The second leg is scheduled for September 15, 2026, at 9:30 p.m. at MorumBIS, according to São Paulo FC's official information. Because lineups, fitness and other absences can change up to kickoff, those points should be checked again on publication day.
São Paulo vs Boca: qualification scenarios
Because Boca won the first leg 1–0, the goal margin in the return match determines the outcome. CONMEBOL states that in the quarterfinals, if the aggregate score is level after the two matches, the tie goes to penalties.
| Second-leg result | What happens on aggregate | Who advances |
|---|---|---|
| São Paulo win by 2 or more goals | Tricolor overturn Boca's 1–0 first-leg advantage | São Paulo advance in regulation time |
| São Paulo win by exactly 1 goal | The aggregate score finishes level | The tie is decided on penalties |
| Draw | Boca keep their one-goal aggregate advantage | Boca Juniors advance |
| Boca win | Boca extend their aggregate advantage | Boca Juniors advance |
That means 1–0, 2–1, 3–2 or any other São Paulo win by one goal sends the tie to penalties. A 2–0, 3–1, 4–2 or any victory by two or more goals sends São Paulo to the semifinal without a shootout.
Is there extra time if the aggregate score is level?
Not in this scenario. The rule communicated by CONMEBOL for the quarterfinals is direct: a level aggregate score after the two matches leads to penalties. Therefore, a one-goal São Paulo win does not produce another 30 minutes; the 90 minutes end with the aggregate score level and the tie moves to a shootout.
Does a Boca goal change the qualification rule?
It increases the number of goals São Paulo need to score, but it does not change the required margin. If Boca score at MorumBIS, for example, São Paulo would still need to finish the second leg one goal ahead to force penalties or two goals ahead to advance directly. A 2–1 São Paulo win levels the aggregate score; a 3–1 win sends São Paulo through.
That is why the aggregate score — rather than only São Paulo's raw goal total — is the most useful reference while following the match.
Why Calleri's suspension matters in the second leg
Jonathan Calleri received his third yellow card in the first leg and is suspended for the decider at MorumBIS. UOL's report on the suspension confirms that the striker cannot play in the return match. After the game in Argentina, Dorival Júnior described the absence as a considerable loss, highlighting the center forward's importance and role as captain.
The impact is not only about the name on the team sheet. Calleri is a central penalty-box reference and provides a physical presence for duels, crosses and occupying center backs. As a tactical interpretation, not a confirmed lineup, his absence is likely to require a different distribution of attacking roles: more movement among the forwards, another player occupying the central zone or rotation between players in that area.
On the eve of the match, UOL reported Luciano as the likely starter and one of São Paulo's main attacking options. That should not be treated as an official lineup before the team is announced.
What São Paulo need to manage over the 90 minutes
- Chase the win without turning urgency into disorder: one goal already brings the tie level on aggregate, but conceding also raises the number of goals Tricolor need.
- Maintain a penalty-box presence without Calleri: the team must compensate for the absence of its reference striker to turn possession and pressure into clear chances.
- Understand the score in real time: a one-goal win means penalties; a win by two or more means direct qualification; a draw or defeat favors Boca.
- Be ready for a shootout: because a narrow win leads to penalties, takers and goalkeepers may decide the tie even if São Paulo win in regulation time.

What matters before kickoff
The scenario is clear: São Paulo need to win by two goals to advance directly or by one goal to send the tie to penalties. Boca advance with a draw. Tricolor must attempt that comeback without Calleri, who is suspended after his third yellow card.
Because the match is on September 15, one final check of lineups, new injuries, suspensions and official notices is advisable before publication. The date, time and stadium can be confirmed on São Paulo FC's official page, while the first-leg report records Boca's 1–0 win and the resulting second-leg scenario.
