Neymar's penalty was the only goal of the game as Brazil beat Uruguay at Arsenal's Emirates Stadium in London.
In a fiercely contested fixture Uruguay asked plenty of questions, adopting a robust approach, but Brazil prevailed thanks to Neymar's composure from 12 yards.
"I'm happier than after the last matches, because we had an opponent who plays you better, makes you work both defensively and offensively," the Paris Saint-Germain forward told the 'Daily Mail'.
"It was as we imagined. We knew that Uruguay don't give you much space and that it would be a difficult game because Uruguay are great in the air and there are two strikers who are the biggest in football.
"We knew it would be difficult. But we found ways to play our football and we found ways to be able to impose our rhythm, create chances to score and get the victory.
"We are leaving here happy. But we have to improve still. We know we can be better. We know we have to adjust things, which I think will help our team and our football.
"But anyway, we are very satisfied today with everyone. I congratulate everyone for this game."
The penalty award against Diego Laxalt was controversial but Neymar made no mistake to score his 60th goal in 95 appearances for the national team.
