Boca Juniors vs Sao Paulo Turns After Halftime

São Paulo began with calmer possession and found space around Boca’s midfield line. Luciano forced Álvaro Montero into a strong save after Iago’s measured cross.

Calleri then attacked another delivery but sent his effort away from goal. However, Boca gradually reduced those gaps and raised the pressure after fifteen minutes.

Leandro Paredes started directing the tempo from deeper areas with greater authority. Therefore, Alan Velasco received cleaner passes between São Paulo’s midfield and defence.

Lautaro Blanco also pushed higher, stretching Lucas Ramon along Boca’s left channel. Meanwhile, Merentiel kept the central defenders occupied through constant diagonal movement.

Rodolfo Arruabarrena kept his structure unchanged during the interval. As a result, Boca restarted with better spacing and faster circulation around Paredes.São Paulo still defended compactly, while Arboleda tracked runners across the back three.

Merentiel Converts Boca's Strongest Move

In the 52nd minute, Boca finally converted its growing territorial control. Paredes allowed a pass to run, which accelerated the move through midfield.

Santiago Ascacíbar shifted possession wide before Velasco released the overlapping Blanco. Blanco’s low cross reached Merentiel inside a crowded penalty area.

Rafael blocked the striker’s first effort at close range with his head. However, the rebound returned directly toward Merentiel with the goalkeeper grounded.

The Uruguayan reacted first and drove the loose ball into an exposed net. Therefore, Boca earned the reward for increasing its tempo after halftime. The official CONMEBOL match report credited Merentiel with three tournament goals.

Arboleda Starts as Valencia Waits

Boca Juniors vs Sao Paulo also carried a national subplot. Robert Arboleda started on the right of São Paulo’s three man defensive line.

Arboleda completed all 90 minutes and handled several direct duels with Merentiel. However, Blanco’s overlap exposed the wider channel before the winning goal.

Meanwhile, Valencia replaced Velasco in the 85th minute for Boca. His brief appearance offered physical presence but produced no scoring opportunity. Valencia then received a yellow card during stoppage time near midfield.

As a result, El Comercio’s account of Valencia’s drought recorded six scoreless Boca appearances. The Ecuadorian striker needs rhythm, service, and longer minutes to regain confidence. Still, Arruabarrena currently trusts Merentiel as the central reference in major matches.

The First Leg Leaves Everything Alive in Brazil

São Paulo pushed forward after conceding and forced Montero into more work. Domingos Duarte attacked one loose ball, while Calleri tested Boca’s goalkeeper again.

However, Montero protected his area with firm handling and sensible positioning. Referee Piero Maza later showed Duarte a direct red card after tackling Paredes.

VAR then advised a review because the defender had contacted the ball first. Therefore, Maza cancelled the dismissal and allowed São Paulo to retain eleven players.

Calleri also received a booking after an exchange with Tomás Belmonte. Consequently, São Paulo will lose its captain through suspension for the return match. The official São Paulo match report confirms the return at MorumBIS on September 15.

Boca Controls the Spaces After Taking the Lead

Boca succeeded because its midfield corrected the distances that troubled the opening phase. Paredes moved the ball earlier, while Ascacíbar supported both pressing and circulation.

Moreover, Blanco created the width that São Paulo’s narrow defensive shape surrendered. Merentiel supplied the decisive quality by following his first shot immediately.

After scoring, Boca resisted the temptation to attack with reckless numbers. Instead, the hosts slowed selected phases and protected central passing lanes.

Consequently, São Paulo depended increasingly on crosses and second balls. Montero then completed the plan by responding whenever those deliveries became dangerous. Boca’s official match account also recorded a third consecutive 1-0 victory.

São Paulo Needs Sharper Finishing in the Return

São Paulo’s performance offered enough evidence that this tie remains competitive. However, wasted first-half chances now carry a heavier cost before the home leg.

Dorival Júnior must replace Calleri without weakening the team’s penalty-area presence. Therefore, André Silva or Gustavo Santana could assume greater attacking responsibility.

Arboleda must again manage Merentiel’s movement while protecting the channels beside him. Meanwhile, Valencia faces a different battle for meaningful minutes within Boca’s attack.

The veteran remains Ecuador’s reference, yet reputation alone cannot settle selection decisions. Boca next hosts Central Córdoba before travelling to São Paulo. The official match highlights show how narrow the first-leg margins became. São Paulo must win by two goals, or by one goal to force penalties.
