Brazil made a terrible start to their Copa America campaign as they were held to a goalless draw by minnows Venezuela in La Plata.
The defending champions looked devoid of ideas and Venezuela had chances to secure a shock win with Brazil looking anything but solid at the back.
Mano Menezes' side had opened confidently and dominated possession, with Paulo Henrique Ganso to the fore, but they struggled to break down a packed Venezuelan defence.
Andre Santos was another to look lively but the best chance of the opening half fell to AC Milan striker Alexandre Pato, who hit the crossbar after being set up by Daniel Alves.
Brazil had appeals for a penalty turned down when a Robinho shot was deflected away for a corner by Oswaldo Vizcarrondo, with the referee deciding the ball had not struck the defender's arm.
Menezes sent Fred, Elano and Lucas on after the break in an effort to inject some life into a stale performance but they remained unable to create genuine clear-cut chances.
And during the final quarter they found themselves under pressure as Venezuela counter-attacked sharply as their more illustrious opponents desperately pushed for a winner.
Juan Fernando Arango failed to capitalise after being set up on the edge of the Brazil box while Tomas Rincon was also off target.
Neymar attempted to carve out a late winner for Brazil but Venezuela held out for one of their most famous results.
