Colombian giants Millonarios overturned a 3-1 first-leg deficit on Tuesday night to advance to the Copa Sudamericana quarter-finals with a 4-3 aggregate victory over Palmeiras. The hosts had it all to do heading into the second leg in Bogota but got off to a fine start when Juan Esteban Ortiz opened the scoring 10 minutes before half-time. A penalty from Wason Renteria just after the hour and a 77th-minute volley from Lewis Ochoa completed the impressive turnaround for the Blues, who finished the match playing against 10 men after Palmeiras substitute Betinho was sent off. Gilson\'s men will next meet either Brazilian team Gremio or Ecuadorian outfit Barcelona. The Porto Alegre-based side head into Wednesday\'s second leg 1-0 up. Cerro Porteno progressed to the last eight on Tuesday, the Paraguayan team securing another 2-1 win over Colon to oust the Argentinian side 4-2 overall. Emmanuel Gigliotti silenced the Asuncion crowd when he headed home Jorge Achucarro\'s cross to put the visitors ahead after only 60 seconds. But 10 minutes later Roberto Nanni equalised after neat play between Fidencio Oviedo and Jonathan Fabbro, and then Julio Dos Santos put the result beyond doubt in the 70th minute. The closing stages were marred by violence in the stands, with the match suspended for around 20 minutes due to trouble between the two sets of fans. Tere was more drama after the resumption with red cards to Colon duo Diego Pozo and Maximiliano Caire 13 minutes from time. Cerro Porteno will next face the winners of the tie between Argentinian side Tigre and Deportivo Quito, who will do battle in the second leg in Victoria City on Thursday night with the Ecuadorian team 2-0 up after the first meeting.
