São Paulo host Boston River at Morumbi on 26 May 2026, the sixth and final matchday of Copa Sudamericana Group C, with kickoff around 3:00 PM local time. The Brazilian side comes in with nine points from five matches and an unbeaten group stage record, while the Uruguayan visitors sit bottom on three points. The first leg in April ended 1-0 to São Paulo through a Damián Bobadilla strike, giving the hosts a buffer heading into the close. These clubs have met only that once in continental competition, so group stage trends carry more weight here than any kind of rivalry.
Dorival Júnior took charge of São Paulo in mid May 2026 following a turbulent spell that cycled through Hernán Crespo, Roger Machado and caretaker Milton Cruz, while Ignacio Ithurralde has been in charge of Boston River since March 2026. They have no history against each other.

São Paulo are unbeaten in five Sudamericana outings, winning two and drawing three, with a defensive solidity that holds even when domestic results slip. A 1-1 draw with Botafogo and narrow defeats to Fluminense and Juventude in Série A suggest a side that loses focus in the league but tightens noticeably when the stakes feel higher. Boston River have won just once in five group games, making this a final day of limited ambition for the visitors.
São Paulo are without Sabino and Maik through injury, Lucas Moura is out for the season with an Achilles issue and Ryan Francisco will not be back until early June after cruciate ligament surgery. Luciano and Cauly are being monitored, though the returns of Marcos Antonio and Rafael Tolói to training are welcome and Boston River have no major absences heading in. São Paulo likely line up in a 4-2-3-1 with Rafael in goal, a back four of Lucas Ramon, Alan Franco, Osorio and Wendell, Danielzinho and Pablo Maia in midfield and Tapia, Artur and Calleri in attack. Boston River should set up in a 5-3-2 with Bruno Antúnez in goal, Rivero, Martín González and Ignacio Fernández in defence and Yair González and Gastón Ramírez leading the attack.

Calleri's aerial ability, backed by corners and wide free kicks from Wendell and Alan Franco, is São Paulo's most reliable attacking weapon throughout this group stage. Boston River's 5-3-2 is designed to deny space centrally and force São Paulo wide, with Yair González as the outlet when they win the ball back. If Pablo Maia and Danielzinho get on top in midfield, Boston River's defensive block will be under sustained pressure with little recovery time, while the wide duels between Wendell and Lucas Ramon against Vázquez and Alexander González could pull Boston River's shape out of alignment and leave Calleri in more space centrally - which makes São Paulo's dead ball delivery worth watching closely throughout.
A 1-1 draw feels right here. São Paulo have the squad depth, home advantage and a first leg buffer to play controlled football without really pressing for more and that measured approach tends to leave gaps for a side with nothing to lose. Calleri or a set piece routine could put the hosts ahead but if São Paulo push Wendell high and leave space in behind, González is the player most likely to punish it.
