Gremio, Union advance as Emelec fall

Brazilian side Gremio progressed to the Copa Libertadores last 16 following a 2-0 away win over Colombian giants Atletico Nacional. The Estadio Atanasio Girardot saw Enderson Moreira's side clinch the qualification thanks to second-half goals and a great performance by goalkeeper Marcelo Grohe.

After a goalless first period, Gremio took the lead after 53 minutes; Luan went down the right and crossed the ball for Dudu who shot over Franco Armani's body. Then, in the 68th minute, Argentinia striker Hernan Barcos stole the ball and beat Armani.

Gremio took sole lead in Group 6 with 11 points, three above Newell's Old Boys of Argentina and four more than Atletico Nacional. Chilean side Union Espanola made it into the round of 16 too, thanks to a surprise 1-0 win over Botafogo in their trip to Brazil.

Jose Luis Sierra's side clinched their very first win in Brazilian soil thanks to a goal by Gustavo Canales at the Maracana Stadium. Twenty-four minutes after the interval, defender Julio Cesar fouled Union Espanola striker Sebastian Jaime in the box and Canales turned that penalty into the winning goal.

Union Espanola reach the nine-point mark thanks to this victory and head Group 2, having progressed with still one more round to go in the Group Stage. Botafogo would have qualified if they had beaten Union Espanola tonight, but must clinch at least a draw in their visit to Argentinian champions San Lorenzo to do so.

Flamengo remain alive in Group 7 as they saw-off Ecuador's Emelec 2-1 as visitors. An injury-time goal by forward Paulinho helped Jayme de Almeida's Flamengo level Mexico's Leon on seven points, one below leaders Bolivar of Bolivia. Alecsandro - for Flamengo - and Denis Stracqualursi - for Emelec- netted the previous goals from the penalty spot.
