Overview

• The second leg is Wednesday at 21:30 (ART) in São Paulo, and River must win by one to force penalties or by two to advance.
• Gallardo is considering a back four versus a three or five at the back and could exclude Enzo Pérez from the starting lineup.
• Sebastián Driussi has been ruled out through injury, prompting a change in attack.
• Giuliano Galoppo returns from suspension and is expected to start regardless of the formation.
• A 2-0 loss with a rotated team at Atlético Tucumán drew Gallardo’s public criticism and heightened scrutiny before a trip to a country where River has won 4 of 26 Libertadores matches.
