Yeah, they need 3 goals, not even to win the game, but to level the scoreline and prolly take the game to extra time, City have to completely go to sleep for that to happen, and that's not something that happens quite often. City are known for scoring quite a lot of goals, and it is difficult to outscore them, even more by a large margin. The odds are completely in City's favor, if Bayern come into that game all flying forward looking for goals, it leaves gaps in their defense, and City are good at exploiting such, if Bayern are patient to wait for their time, City would be content with that as they already have a huge lead, i cannot see a way back for Bayern Munich.
