Leipzig away is currently going to be very difficult for all Bundesliga teams, including Bayern. That's why I don't see Bayern as a clear favourite. There is also a strong possibility that the match will end in a draw. Both teams are strong and Leipzig had the upper hand in the cup final. Of course, there was no Harry Kane then. There is a stronger Bayern now.
We should expect a draw tie between RB Leipzig and Bayern Munich, with a difficult decision to be reached. However, the Red Bulls have an advantage because it is a home game, giving them a full advantage over the Bavarians. However, we should not draw any conclusions just yet because this is Bundesliga and anything is possible. We discovered that RB Leipzig smashed Bayern Munich in the final, making it a personal task for Thomas Tuchel to fully comprehend the game. Marco Rose will face Thomas Tuchel again, but this time in league game.
Basically, Kane already at Bayern Munich when playing in the German Super Cup final but unfortunately, Kane at that time only played from the bench. Of course, the situation is very different now, we know that Kane has gained good form and or good chemistry at Bayern Munich now. Moreover, at least Leipzig has a difficult schedule too, because after playing against Bayern Munich in the Bundesliga, the reality is that Leipzig will play in the Champions League against Manchester City.
So yes, with such a schedule, then I personally do not believe Leipzig will succeed in getting a good result in the match against Bayern Munich later. Although indeed, at least the chance for a draw remains for Leipzig, but it looks like it will still be difficult for Leipzig considering the schedule they have like that. Therefore, then at least Bayern Munich will also still have a good chance to be able to beat Leipzig at the Red Bull Arena, of course, as a way of revenge.
