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.
What is clear is that even though the second leg is home game for Leverkusen, they will still have difficulty winning big with difference of at least 3 goal to match the aggregate with Bayern Munich, Leverkusen could play well later but try to think more logically that Bayern Munich is already ahead and of course in the second leg they only need to play defensively to prevent Leverkusen from scoring goal and with that Bayern Munich will be the team that will qualify for the next round.
There is no longer much hope but hopefully Leverkusen can show good game to create competitive match so that even though they fail to survive in the UCL they can still make the fans satisfied and not really disappointed because there is still chance next season for the UCL competition.
