Even though Bayern could indeed play more openly and attack because they have to score a lot of goals, I doubt Bayern Munich can do it well. because I saw that Bayern even had bad match results in the Bundesliga. Meanwhile, Man City seems to continue to show their solid strength at the moment in the Premier League. so even for the second leg it seems that Man City will still win and qualify for the semi-finals.
Playing open will become a huge challenge for bayern. It's caused manchester city to have a very good squad at this moment who can played even better if the club was playing fully open. I see that no chance for bayern other than going to be fully offensive.
Three goals aggregates are a lot. It needs a clean-sheet for bayern combined with at least three or four goals to be able to win against manchester city. The problem is if bayern was making a small mistake and this potential to be converted into the goal by manchester city. Bayern needs more than to be careful against manchester city. It needs to consistently defend its goal keeper. Some mistakes will result conceded more goals by city.
It's pure gambling if bayern is willing to take fully offensive against manchester city at this moment. High risk high reward if bayern is still willing to play openly against manchester city.
