With Manchester City needing nothing less than a win to stand any chance of making it to the next round of the competition, Mancini is aware the team cannot afford to repeat their disappointing opening match day performance against Real Madrid.
The City manager told the Daily Mail that it would be imperative for his team to remain focused throughout the course of Real Madrid's upcoming visit to the Etihad Stadium.
"They are one of the best teams in the world, and to beat them, we will have to give a perfect performance. We went close last time, in Madrid, and were 2-1 up with four minutes to go, but this is not going to be easy," Mancini said.
"It is a different game, and if we want to beat them, we will have to defend very well. They have three or four players who can decide a game at any moment, and we are going to have to work very hard as a team."
Going into the game on the back of a dominating 5-0 win over Aston Villa, Mancini believed the City squad are now ready to tackle the challenge presented to them by Los Blancos.
"At least we have improved defensively in the last four or five games, which is important, it is down to the whole team playing different football and having 65 per cent, or more, control of the game. That has helped us look more solid," he stated.
"If you have players who have won World Cups, like David Silva, or who have won everything in the game, like Yaya Toure, you know what you are going to get on nights like this.
"For them, playing against Real Madrid is the essence of football, and it should bring the best out of them. Sergio Aguero will want to make up for that and I think he can cause problems for Real [Madrid]. But, above all, we must play as a team. They have a big history, going back a long way. But I do think we have the players who can beat them. It is possible."
