The first two Copa Libertadores quarter finalists were confirmed on Tuesday evening and it was good news for Argentina as River Plate and Lanús overcame Guaraní and The Strongest respectively.
River held a commanding 2-0 lead over Guaraní from the first leg in Paraguay so were expected to see out the tie in relative comfort back at the Monumental but the Aurinegros ensured there were some nervy moments for Marcelo Gallardo’s side.
With Enzo Pérez making his first start for River, Los Millonarios were the better side for much of the first half but found themselves behind in stoppage time when Marcelo Palau headed in from an acute angle.
What could have been an increasingly nervy second half was swiftly eased when Lucas Alario bundled in a scrappy equaliser in the 51st minute after Guaraní had failed to clear a corner.
River saw out the 3-1 aggregate victory and now await either Jorge Wilstermann or Atlético Mineiro.
A little earlier in La Fortaleza, Lanús managed to edge past The Strongest thanks to some good work from Esteban Andrada in goal and a late goal by José Sand.
After a 1-1 draw in Bolivia, El Granate were holding on for a tense away goals victory when José Luis Gómez split open the visiting defence for Nicolás Pasquini to roll the ball into the path of Sand for a simple finish.
The 2-1 aggregate win means Jorge Almirón‘s side face either Emelec or San Lorenzo in the quarter final.
