The fixture was taken to extra-time following a goalless draw at the Kazan Arena, before eventually reaching a penalty shootout, as the two fought it out for a ticket to Sunday's final.
It was European champions Portugal who came up short, with Bravo denying Ricardo Quaresma, Joao Moutinho and Nani from the spot.
And it has now been revealed what Bravo said to his countrymen before the spot-kicks took place.
"Claudio is extraordinary. He told us before the penalties that he was going to stop two or three," Vidal is quoted by ESPN .
"We looked from the beginning, this selection, as always, shows that in difficult times the commitment, the heart of Chilean, comes out."
Remarkably, after the game, Bravo claimed he was suffering from an injury during the tie but was able to draw on his experience to send Ronaldo and Co. home.
"I feel as I always do. I'm a very balanced person," he said. "I was injured and didn't play at my normal pace.
"But I normally take things calmly and this was a very special game for us. We were able to reach the final which is very important for us, we're completing a very successful cycle. We're happy to play in the final.
