In fact, the 34-year-old was even overconfident as the Selecao headed for spot-kicks in the last 16 of the World Cup - as he told his team-mates that he would save three penalties!
As it happened, two saves were enough for Cesar, with Gonzalo Jara's final kick ricocheting off the post to send Brazil through to the quarter-finals.
But Cesar's confidence beforehand was vital in motivating his team-mates ahead of the shootout, says defender Silva.
"It's impossible to translate this into words, a unique moment in our lives. Before the penalties, Julio told us to be confident on penalties because he would save three penalties," the Paris Saint-Germain defender told reporters after the game.
Cesar himself shed tears of joy after his side's dramatic victory over Chile, who proved worthy opponents over 120 minutes and almost snatched victory when Mauricio Pinilla hit the bar late on.
"I gave an interview four years ago and I cried [when Holland eliminated Brazil]," the Queens Park Rangers goalkeeper told Sportv. "I was very sad but now I am crying because I am happy.
"Only God and my family know what I went through and I still do. My team-mates gave me a lot of support to do my best. I hope to give more interviews like this, this is my dream."
The 34-year-old later joined Toronto FC on loan and how far he has come for Brazil is testament to his iron will and determination. Now just three matches stand between Cesar and the World Cup trophy.
