Colombia's Atletico Nacional into Copa Libertadores last eight

 An Alejandro Guerra brace ensured Atletico Nacional advanced to the Copa Libertadores quarterfinals with 4-2 victory over 10-man Huracan here on Wednesday.

The result gave the Colombian side a 4-2 aggregate victory after a goalless draw in last week's round of 16 first leg in Buenos Aires.

Victor Ibarbo gave the hosts the lead at the Atanasio Girardot stadium before Cristian Espinoza equalized just before the half-hour mark.

The Argentinian outfit were reduced to 10 men when Federico Mancinelli was dismissed for a second yellow card.

Guerra then struck twice in 10 minutes as Atletico made the most of the numerical advantage.

Ramon Abila gave the visitors hope with a 77th-minute goal, but Jonathan Copete guaranteed victory for Atletico with a stoppage-time strike.

Atletico, who finished the group stage with the a competition-high 16 points, are aiming for their second Copa Libertadores title. Huracan have never won South American football's top club trophy.
