Having played their first leg a week earlier, Lanús travelled to Torreón to defend their narrow lead against Santos Laguna and despite another competitive match, Guillermo Barros Schelotto’s side deservedly qualified for the next round for the first time in the club’s history. A first half goal from Ismael Blanco dampened the Mexican hopes and when Lautaro Acosta was bundled over in the penalty box shortly after half time, Paolo Goltz smashed in the second and set up the tricky last 8 tie against Bolivar. In the first legs of their last 16 ties, San Lorenzo will take a slender one-goal advantage to Brazil thanks to Ángel Correa’s fine goal against Grêmio in El Nuevo Gasómetro. A tightly contested still hangs in the balance when the two sides meet again in Porto Alegre next week. Vélez Sarsfield did not fare as well, suffering a late 1-0 defeat in Paraguay against Nacional. Julián Benítez struck with two minutes and despite some initial uncertainty over whether the ball had crossed the line, the officials correctly awarded Nacional the goal. Without an away goal, Vélez are in a precarious position when the two sides meet next week in Liniers. WATCH THE GOALS….
