Bayern Munich will have a busy week and also quite tight matches, first, they will face Leipzig and in the middle of the week against Copenghagen in the Champions League but this may be the easiest match that Munich will face because next in the Bundesliga they will face Freiburg.
Leipzig has a very good memory of being able to beat Bayern Munich with a convincing score in the Super Cup, but that happened when Harry Kane was not yet with Bayern Munich where they experienced difficulties in scoring goals, and this time with Harry Kane who can be said to be productive in his first season in The Bundesliga will help this team to win even though this is an away match for them because H2H Munich is superior and will be the right time to break their two losing streak to Leipzig.
Bayern Munich's performance is currently very good and consistent so of course it will be different from what happened in the previous match against Leipzig, but of course this match will be quite fierce because this is a match between two top Bundesliga teams and also this match will be played at Leipzig's home ground. Of course it will be a little difficult for Bayern.
However, regarding the busy schedule and having to play in the UCL a few days after the match, I don't think it will be a significant problem, especially since Copenghagen is not that difficult for Bayern, which has better quality than them.
