Boca Juniors travels to Brazil to face São Paulo in the return leg of the Copa Sudamericana quarterfinals, holding a narrow 1-0 aggregate lead from the opening match at La Bombonera. The decisive fixture kicks off on Tuesday at 9:30 p.m. local time at the Estádio do Morumbi in São Paulo, matching 21:30 UTC, with a spot in the tournament semifinals on the line.
Team News and Projected Starting Lineup
Head coach Rodolfo Arruabarrena shaped his game plan by resting the majority of his regular starters during the team’s domestic victory against Central Córdoba in the Torneo Clausura, according to match reports. Only defender Lautaro Blanco started that weekend fixture, while midfielder Santiago Ascacíbar made a substitute appearance to preserve match fitness ahead of the continental clash.
The Argentine side welcomes back goalkeeper Álvaro Montero after the Colombian international traveled home following the first leg due to a family bereavement. In defense, Leandro Lozano, Lautaro Di Lollo, Facundo Herrera, and Lautaro Blanco anchor the back line, with Herrera winning selection over Marco Pellegrino to partner Di Lollo while Ayrton Costa continues his recovery from a thigh strain sustained against Racing.
The midfield receives a major boost with the return of Milton Delgado, who recovered from a hamstring strain that sidelined him for four matches. Delgado slots back alongside captain Leandro Paredes and Santiago Ascacíbar in central midfield, forming the unit Arruabarrena regards as his first-choice trio. Further up the pitch, Alan Velasco retains his advanced playmaker role following strong recent performances.
In attack, Miguel Merentiel leads the line as the central forward, flanked by Leonel Flores, who retained his spot ahead of Sebastián Villa. Malcom Braida also returns to the matchday squad after overcoming a muscular injury, providing a defensive option on the bench alongside other selected substitutes.
Tactical Context and Opponent Outlook
Holding a 1-0 advantage requires disciplined defensive positioning and intelligent transitions from the visitors. São Paulo enters the match under pressure to overturn the deficit on home soil, though the Brazilian squad absorbed a 2-0 defeat against Palmeiras in domestic play while resting key players ahead of this quarterfinal second leg.
Arruabarrena’s return to the Morumbi carries historical resonance for the club, recalling previous continental encounters at the historic venue. As the match approaches, tactical discipline in the central areas involving Paredes, Ascacíbar, and Delgado will dictate how effectively Boca can absorb early pressure and exploit open spaces behind the host’s advancing lines.
