Colombia have held Brazil to a 0-0 draw in an engrossing game on Sunday, ending Brazil’s nine-match winning run in the South American qualifiers for the 2022 World Cup in Qatar.
Both teams played an open game in the heat of Barranquilla but neither created many goalmouth chances, particularly in a stunted first hour.
The game came alive in the last 30 minutes as both teams pushed for a winner, but goalkeepers David Ospina and Alisson Becker made excellent saves from long-range efforts to keep the game scoreless.
The result leaves Brazil at the top of the 10-team group on 28 points, nine ahead of Argentina, who play Uruguay later on Sunday. Colombia are fifth on 15 points.
The top four teams qualify automatically for Qatar and the fifth-placed side goes into an inter-regional playoff.
Earlier, third-place Ecuador lost 2-1 on their travels to Venezuela and frustrated fans who were hoping to get closer to a World Cup spot.
Enner Valencia opened the scoring for the visitors from the spot in the 37th minute, but Venezuela responded with goals by Darwin Machis late in the first half and Eduard Bello in the 64th.
Ecuador remain on 16 points and last-place Venezuela have seven.
Bolivia scored a 1-0 win over Peru in La Paz. Substitute Ramiro Vaca drilled home a low left-foot shot with the aid of a deflection in the 82nd minute for the hosts after Henry Vaca was shown a straight red card seven minutes prior.
Peru remain seventh on 11 points and Bolivia improve to eighth nine points.
