Nordi Mukiele is defender and his exit from the match will create wider difference for Bayern Munich to penetrate more freely to attack and that is the reason why in the second half after Nordi Mukiele came out Leverkusen could not do much because they also had to focus on the defense that was no longer intact, if all Bayern Munich chance became goal in the second half maybe this would no longer be lost by 3 goals but more.
Leverkusen chance of equalizing the aggregate score with Bayern Munich are very slim, Leverkusen must win by 3 - 0 more in the second leg match but it seems impossible to do because Bayern Munich themselves in the second leg match will definitely be more careful because their condition is advantaged by an aggregate advantage of 3 points.
It seems that Bayer Leverkusen must think hard to be able to create a surefire strategy in the second leg later because it created three goals in one match in the Champions League with an not easy opponent is a challenge that is quite difficult to solve by Leverkusen. But I am sure Leverkusen will continue to try to be able to make it happen even with a very heavy taste and even if it is not successful, at least Leverkusen is only inferior to the conditions that are so honorable because they have tried as much as possible.
