Tite sent videos of his previous work to the Brazil squad to aid their transition to his philosophy ahead of his first match at the helm.
Former Corinthians boss Tite was appointed as the successor to Dunga in June after the Selecao failed to progress beyond the group stage at the Copa America Centenario.
Ahead of Thursday's match against Ecuador, Casemiro told a news conference: "They are videos of his work, of what he will ask for on the pitch.
"Before we came here, he had already sent a video to us. It's no secret.
"Now, speaking with him, you understand better what he is asking, but it is important we arrived here already with the philosophy that he wanted."
"It is not the time to put on a spectacle, it is time to play and win," said Casemiro.
"We have to think game to game, first of three points on Thursday, and then of Colombia.
"Only after we can think of putting on a spectacle, of doing what the Brazilian people hope of us.
"The moment is to win and earn three points."
"Statistics are there to be broken. We know the game will be very difficult, but we are focused and confident that things will turn out well," continued the midfielder.
"We arrived on Sunday to adapt to the altitude and the speed of the ball."
