The Blues are in Istanbul for this weekend's showpiece occasion, kicking off at the Ataturk Olympic Stadium at 20:00 (UK).
Having already lifted the Premier League and FA Cup this season, Guardiola's side are just one win from an historic Treble.
While the boss admitted that is a 'dream' scenario, he has called for his players to focus on the task at hand, no matter what opposition are doing.
Speaking in Friday's press conference in Turkey, he said: "We have to be patient. The most important thing in this type of game is thinking we are 0-0 and thinking we are losing.
"Italian teams are 0-0 and think they are winning. They are not winning it is 0-0. We have to be stable and get rhythm and be stable.
"In bad moments we need to step forward. It will happen. 1-0 down or 1-0 up so in both circumstances be stable."
City have overcome RB Leipzig, Bayern Munich and Real Madrid already in the knockout stages of this year's competition, sticking closely to the plan set out by Guardiola and the coaching staff.
Asked whether he would look to give his players more freedom in the final, our manager insisted his players should stick to his methods.
Although he did suggest that he will be flexible if the situation demands it.
"The plan gives us stability and helps in certain moment sin the game to come back and have security," said Guardiola.
"It’s important in the final to have a plan. But finals are one off games and if it goes bad, we can put more strikers.
"Or maybe we put seven central defenders, I don't know. There are moments when it will be, guys, there no tactics here. It’s just desire we have to go."
The Catalan was also adamant that the result of our last Champions League final - a 1-0 defeat to Chelsea in 2021 - will have no bearing on this match.
"It’s a different game, two years later, different players," he stated.
"What we planned two years ago was to do a good game v Chelsea. It did not work. That's why people say it was wrong.
"Tomorrow will be the same. I will have a plan. We are ready - I have the feeling the players will give absolutely everything. Go for it!"
