Neymar, Dani Alves, Hulk and Willian found the back of the net in Brazil’s second last warm-up match before kicking off the World Cup against Croatia on June 12.
“I still have concerns, but not at the same level I had on Sunday,” Scolari said after the match.
“We did not allow our opponents the opportunity to counter-attack and that is what I need to see because our team has the quality to score one or two goals.
“If we do not allow our opponents easy counter-attacks we have a chance to win games by even by more. We improved, but we still have a long way to go.”
Brazil are in Group A along with Mexico, Cameroon and Croatia.
