Both teams had 100 per cent records approaching the match at the Estadio Centenario in Armenia in Colombia, but the defending champions laid down a serious marker with the heavy scoreline.

Bia Zaneratto headed Brazil into a 1-0 half-time lead, before Ary Borges finished off a counter-attack with a classy strike and Debinha added a brace from close range.

Debinha now has four goals in the Copa América Femenina, tied for the tournament lead with team-mate Adriana and Argentina's Yamila Rodríguez.

The victory means Brazil are now assured of a spot in the semi-finals and will win Group B, not that that ever looked in much doubt.

Uruguay smashed Peru 6-0 later in the day at the same venue.

It was goalless at the break, but Pamela González and Esperanza Pizarro both scored twice in a stunning second-half showing from Uruguay.

It was Uruguay's last match of the tournament as like Peru they have been eliminated.

Venezuela and Argentina are level on six points and will meet in a winner-takes-all clash on Thursday (July 21) to decide who finishes second in Group B.

Argentina have the better goal difference, so would reach the semi-finals should there be a draw.
