CONMEBOL’s decision earlier in the day to award Lanús a 3-0 victory over Chapecoense due to an ineligible player netting the Brazilian side’s winner last week had already sent El Granate through to the Copa Libertadores last 16 but Lanús ensured top spot in Group Seven with victory away to Nacional.
Alejandro Silva’s delightful clipped finish over Esteban Conde midway through the first half was enough for all three points.
Nacional went through in second place and Chapecoense’s dramatic late win over Zulia booked a spot in the Copa Sudamericana.
So far only Estudiantes have failed to reach the knockout stages from Argentina’s six representatives. Atlético Tucumán play Palmeiras on Wednesday needing a win to avoid being the second.
