Overview

• Captain Gustavo Gómez headed in from an Andreas Pereira corner at 6 minutes and Vitor Roque doubled the lead before halftime, before Lucas Martínez Quarta pulled one back late for River.
• VAR checked a possible penalty after Weverton collided with Montiel, but an offside in the buildup canceled the review and the goalkeeper was cautioned.
• Andreas Pereira marked his Palmeiras Libertadores debut with the assist on the opener as Abel Ferreira’s choice to start him over Facundo Torres paid off.
• Marcelo Gallardo and Argentine outlets said the late goal keeps River alive, and the defeat was River’s first at the renovated Monumental in the competition.
• The second leg kicks off at 21:30 (Brasília) on September 24 in São Paulo, where a draw sends Palmeiras through, a one-goal River win forces penalties, and a margin of two or more advances River.
