Universidad de Chile has progressed to the second stage of the Copa Sudamericana, a 5-0 home win sealing a 6-3 aggregate victory over Bolivia's Real Potosi.

Isaac Diaz and Charles Aranguiz each bagged a brace to help Marco Antonio Figueroa's side overturn its 3-1 first-leg deficit in style.

Diaz opened the scoring in the 31st minute with a header and Aranguiz added a second by converting a penalty 10 minutes later.

The host continued in the same vein after the interval and Aranguiz made it 3-0 with a right-footed strike from outside the box just before the hour, with another spot-kick - this time scored by Diaz - stretching the lead two minutes from time.

There was still time, however, for Argentinian midfielder Gustavo Lorenzetti to add his name to the scoresheet and seal the rout in stoppage time.

Figueroa was thrilled with his team's display, telling reporters in Santiago: "We must play always this way.

"I've always been satisfied with the individual and group job, but I want to highlight the team job. We played a great match tonight, with very high peaks."

Universidad de Chile, which won the Copa Sudamericana in 2011, will next face Ecuador's Independiente del Valle or Deportivo Anzoategui of Venezuela.

They drew 0-0 in their first meeting and will go head to head to decide the tie on Thursday evening (friday AEST).

John-Edward Valoy's double lifted Atletico Nacional to a 4-0 victory over Peru's Inti Gas, completing a 5-0 aggregate triumph for the Colombian giant.

As well as notching in the 18th and 63rd minutes, Valoy provided the assist for Juan Pablo Angel to net in the 33rd minute.

Angel fired a penalty against the post in the second half before Elkin Calle rounded off the scoring.

Valoy told Fox Sports: "The week's work had its rewards on the field tonight. We did our job very well, but we must keep working ahead of the next games."

Another Colombian team to advance to the next stage was Pasto, which suffered a 2-0 away defeat to Melgar in Peru but progressed thanks to last week's 3-0 home win.

Oscar Gamarra and Ysrael Zuniga netted for Melgar in the first period but the Peruvian team failed to force penalties.

In Montevideo, Sebastian Taborda notched two goals as host River Plate hammered Blooming 4-0 to seal a 5-0 aggregate win.

Taborda opened the scoring seven minutes before half-time from Cristian Techera's assist.

Michael Santos made it 2-0 five minutes after the interval and Taborda stretched the advantage still further just after the hour mark, before Techera added his name to the scoresheet nine minutes from time.

Liga de Loja of Ecuador also advanced with a 1-1 away draw against Venezuela's Deportivo Lara.

Jose Torrealba put the home side ahead with a bicycle-kick in the 21st minute but Santiago Barboza equalised with a minute remaining to hand Liga a 3-1 aggregate victory.

Both teams ended the match with 10 men, with Lara defender Luis Colmenarez and Liga midfielder Pedro Larrea shown red cards.
