Rio De Janeiro, Mar 9: Flamengo moved atop Group 2 of the Copa Libertadores after Vagner Love scored a second-half goal in a 1-0 win over a 10-man Emelec on Thursday.
In Argentina, former River Plate striker Leandro Caruso scored three goals, including a 90th-minute equalizer, as host Godoy Cruz drew Atletico Nacional of Colombia 4-4.
Ronaldinho set up Vagner Love's goal in the 49th minute at the Engenhao stadium in Rio, but the two-time FIFA player of the year was jeered by Flamengo fans after another poor performance.
The victory moved Flamengo to the group lead with four points, one more than Paraguay's Olimpia and Emelec. Lanus of Argentina has one point. All teams have played two matches.
Vagner Love scored the winner for Brazil's most popular club with a low left-footed strike from inside the area after a well executed give-and-go play with Ronaldinho. It was the fifth goal in as many matches for the former CSKA Moscow player.
Ecuador's Emelec played a man down from first-half injury time because forward Marlon de Jesus was sent off after a ball dispute near midfield. The referee said he elbowed Flamengo defender Wellinton while going for a high ball.
Flamengo struggled despite playing with the extra man the entire second half, allowing the Ecuadoreans to threaten a few times.
Ronaldinho said he was not bothered by the fans' complaints.
"It gives me more motivation to try even harder the next time," Ronaldinho said. "What was important is that we got the win."
Vagner Love agreed: "We got the three points, we did what we were supposed to do at home. We got only one goal, but it gave us the victory, that was the goal."
Flamengo will host Olimpia next week, while Emelec will play at Lanus.
In Mendoza, Caruso netted the equalizer with a right-footer from the top of the area. His other goals came in the eighth and 69th minutes. Godoy Cruz also scored with Ruben Ramirez in the 33rd.
Atletico Nacional got goals from striker Dorlan Pabon in the 55th and 70th minutes, while Luis Fernando Mosquera netted in the 13th. The team's other score came after an own goal by Godoy Cruz defender Leonardo Sigali in the 29th.
The Colombians reached seven points from three matches to remain atop Group 8. Universidad de Chile has four points, along with Godoy Cruz.
Penarol of Uruguay, last year's runnerup to Santos, has only one point in last place, also after three matches.
The top two teams from each group will advance to the next round.
