Scolari's men scraped past Serbia 1-0 in Sao Paulo on Friday, courtesy of Fred's 58th-minute goal.
The host nation's fans were unimpressed by the showing, venting their displeasure at the final whistle at the Estadio Cicero Pompeu de Toledo.
"Yes, we do," Scolari replied, when asked if his side leans on Neymar too much.
"As Portugal needs Cristiano Ronaldo or Argentina relies on (Lionel) Messi as well.
"We need Neymar as every team that has good players that attract opponents, needs as well.
"Our duty is to find solutions in the field when Neymar is facing too many opponents on him."
"I believe it's normal. This is normal when we are not performing well. They booed us in Goiania as well," Scolari said.
"They (the players) are prepared for that. They know that when we are not playing well the fans will be upset.
"But in the end I believe that the majority of 67,000 who were here left the stadium happy with the result.
"So we must thank the fans because they were patient and helped us to achieve this win."
"We knew it was going to be tough, but it was good to face a tough opponent," the Chelsea man said.
"They are very strong in the back. It was a tough match but we won it and that's what we want during the World Cup.
"I'm not worried about the critics. Obviously the press keep saying things like that and the fans listen to you.
"But I am very calm. I played well in Goiania. Today was hard for everyone. No-one played well during the first half.
"Obviously you know my potential so there is more criticism."
