After an opening 2-0 defeat to Mexico, Dunga's side got their Group B campaign back on track as the 23-year-old striker broke the deadlock from the spot in the first-half before adding two late goals to seal the points.

"I know I played a crucial role but the whole team played very well," Robinho said.

"We have to improve our finishing though because we had quite a lot of chances to score and we need to make them count.

"We have to keep playing like this and we'll have more confidence."

Defender Juan believes there is more to come from Brazil when they take on Ecuador on Wednesday as the defeat to Mexico meant they were at risk of elimination if they did not beat Chile.

"We hadn't expected a defeat to start with but we are improving day by day and I hope we can play even better against Ecuador," he said.

"Our finishing was better today, we had more luck and Robinho was inspired."

Vagner Love, who set up the second goal for Robinho, added: "We'll improve on certain aspects and play even better against Ecuador."

Midfielder Mineiro praised Brazil's team spirit.

"We enjoyed ourselves on the pitch," he said.

"If keep this up, we'll play better and better as the tournament goes on."

Chile coach Nelson Acosta admitted he faces selection problems ahead of the crucial clash with Mexico.

Miguel Riffo, Jorge Valdivia and Rodrigo Melendez ended the game with injuries - Riffo may have torn a muscle in his leg, while Melendez twisted an ankle and Valdivia is suffering with a neck problem.

Acosta said: "Melendez's injury is probably the most worrying because it seems to be a serious twist.

"We'll see how we can solve these problems in training."

Meanwhile, defender Pablo Conteras believed Chile could take some positives from the defeat.

"Up until the final few minutes, we played good football and could have equalised," he said.

"I think we have to be more composed during crucial moments to control the game better.

"We had more clear-cut chances than Brazil but they took the ones they had."

Alvaro Ormeno agreed, adding: "You can see it as a hammering but I think 3-0 isn't a fair scoreline.

"Brazil knew we were very close to equalising and then profited from two defensive mistakes to kill the game off."
