Playing with an attacking style against a team like Manchester City with the strong forwards they have is not a wise move at all, because if they use the counter-attacks, especially with super fast midfielders and forwards they have, That's why I think Bayern Munich won't have any chance even in the second leg to beat Manchester City and they need a miracle.
I think Bayern Munich has a chance to beat Manchester City in the second leg, I mean Bayern Munich will win but they win with small margin for 1-2 goals, I don't expect they can score at least 3 goals. Bet on Bayern Munich in moneyline option is quite profitable since the odds is @2.70.
Usually when the club already secured the first leg with big margins, they're not aiming to score more goals, but they just make sure they will qualify for the next round.
