It will be an interesting match! Bayern are top of the table but lost to Mainz and are missing players like Neuer and Coman, so they need to play well. Fortunately Muller and the midfield are here... I know that Leipzig have won their last two games and they won't be an easy opponent. But the fact that Bayern haven't lost their last game of the year since 1984 is something crazy 
Well, statistically, Bayern will win.
Bayern Munich who will play at home in this match does not mean that they can easily win the match today, because Leipzig also have the determination to beat Munich in this match so that Leipzig can reduce the points gap with Munich in the Bundesliga standings. Moreover, this season Munich's speed in making a gap with their rivals is also quite extraordinary so that any team will take advantage of the moment very well when Munich is not strengthened by Neuer and Coman. So Munich must be more careful in this match if they want to win because Leipzig will also build a more dangerous attack in this match. Well, statistically, Bayern will win. I don't think anyone will be expecting the match to be easy for Bayern Munich because Leipzig are also in good form. However, I still see Bayern Munich as the favorite team to win the match, despite knowing that Leipzig are currently performing well.
It is Bayern Munich's home match, and I expect more effort from them, even though some of their players are injured. They need to win this match because losing today would decrease their chances of winning this season's Bundesliga. Bayern Munich are currently just four points behind Bayer Leverkusen.the least performances I expecting from Bayern Munich is a draw if they can't win against Leipzig today.
