Bayern Munich's survival in the Champions League is now very difficult as I don't think they can beat Manchester City in the second leg. That's why Bayern Munich is now expected to focus heavily on the Bundesliga. Because Bayern Munich has the potential to win the Bundesliga title.
As long as Bayern Munich can work well as a team, there will be a chance to win against Manchester City. Some of the teams that have beaten Manchester City use good teamwork and always guard their attacking players like Erling Haaland, so it's not easy to get the ball and there's no chance for Manchester City to score.
Manchester City had a huge advantage in the first match. Even if Bayern Munich wins in the second leg, they need to score at least 3 goals in order to carry the game into overtime. Also, they should not concede. Bayern Munich will have a tough rematch. It is not easy to beat Manchester City.
There are still opportunities for Bayern Munich, it's just that the percentage has become smaller after they lost 3 goals in the first leg. Scoring more than 3 goals against Manchester City is not an easy task, I even see Manchester City having the potential to score in the second leg later. But giving up just like that is also impossible, because they have to try and hope that luck in the second leg will be on Bayern Munich's side.
