Colombia bounced back from Sunday's shock 1-0 Copa America loss to Venezuela with a 1-0 win over Brazil on Wednesday.
Centre back Jeison Murillo struck the winning goal in the first half, smashing a loose ball into the bottom corner after Brazil failed to clear a Juan Cuadrado cross.
The result leaves Colombia and Brazil locked on three points ahead of tonight's game between Peru and Venezuela, which could dictate which of the two big teams make it through.
Murillo was the hero with his first ever goal for Colombia, but the man of the match was arguably midfielder Carlos Sanchez, who of course plays his club football for Aston Villa.
The defensive midfielder had an up-and-down debut season in English football having made the move to Villa Park from Elche last summer, which followed an impressive World Cup campaign from the 29-year-old.
Back with Jose Pekerman's side, Sanchez was exceptional in front of the Colombia back four, racking up five tackles and five interceptions according to WhoScored, preventing Brazil from equalising.
The most impressive part of his display was that he totally nullified the threat of Brazil's star man Neymar, dominating the Barcelona hero throughout.
Sanchez's performance will give Aston Villa fans hope that he can produce similar displays in his second season at the club, with manager Tim Sherwood no doubt looking for the Colombian no transfer his international performances to the club scene.
