Brazil head coach Tite felt his side were worthy victors following Miranda's 93rd-minute winner on Tuesday.
Tite insisted Brazil were better than Argentina after claiming a last-gasp win over their South American rivals.
Brazil top dogs
Brazil edged past a Lionel Messi-less Argentina 1-0 in Saudi Arabia on Tuesday courtesy of Miranda's 93rd-minute winner.
Tite's Brazil were far from convincing in attack as they struggled to create any clear-cut chances, with Argentina appearing set to earn a draw in the sapping Saudi heat.
That was until veteran centre-back Miranda headed home in stoppage time and Brazil head coach Tite felt his side were worthy victors.
"Argentina created chances to score, tried to win, but Brazil were better and the team's performance was rewarded with the goal," Tite told reporters.
Tite added: "It [Miranda's winner] could have been another time, but it was in the end.
"The team were concentrating. The corner was the result of a volume of play that we put in the game."
Mirando the hero
Miranda was the difference in the international friendly, the unmarked Inter defender rising highest to settle the contest.
"I am very happy, first, to help my team-mates, and to make a goal against Argentina is exciting and rewarding," the 34-year-old said.
"I dedicate the goal to those who trusted and supported my family. Today I met my wife 16 years ago. and I'm excited, making a goal is very difficult... A kiss for my wife and my children, I want to celebrate the goal with them."
