Brazil beat Chile 3-0 at the unfinished Monumental stadium on Sunday with Robinho scoring a hat-trick.
Despite the scoreline, Brazil were far from convincing for most of the game and spared by poor Chilean finishing in the second half.
Brazil struggled to find a way through Chile's packed defence early on and Robinho, apart from a couple of trademark stepovers, saw little of the ball.
But they were gifted a chance in the 36th minute when Gilberto's cross from the left was comfortably held by goalkeeper Claudio Bravo but the referee gave a penalty, apparently for pushing.
Robinho calmly scored with a low shot which just eluded Bravo's outstretched hand.
Chile came out fighting after halftime and striker Humberto Suazo was close from a free kick. Shortly afterwards, the shaven-headed Suazo was put clean through but delayed and, by the time he shot, there were three Brazilian defenders on the line to clear the ball.
Jorge Valdivia wasted another chance when he shot straight at a defender from close range. Robinho finished the Chileans off in the 84th minute when he latched onto Vanger Love's pass and chipped over Bravo.
Three minutes later, he collected the ball 40 metres from goal, dribbled past two defenders and scored with a shot into the corner.
