Overview

• River trail 1-2 on aggregate after losing the quarterfinal first leg at the Monumental and need a positive result on Wednesday night at Allianz Parque.
• Marcelo Gallardo is weighing a system switch between a back five and a 4-3-3 and could replace Enzo Pérez with Juan Portillo as the lone holding midfielder.
• Giuliano Galoppo returns from suspension, Lautaro Rivero is expected to be available despite a muscle issue, and Facundo Colidio and Juan Fernando Quintero could keep their places despite poor form.
• The domestic slump includes a defeat at Atlético Tucumán that ended a 15-match away unbeaten run and marked River’s first consecutive regulation losses since Gallardo’s return, dropping them behind Riestra in Zona B.
• Gallardo told players the tie remains possible with the right mindset, while 2,000 River fans will attend in Brazil and Andrés Matonte will referee the second leg.
