Leverkusen is currently only 2 points behind Bayern Munich. So if the Bayern Munich team can beat Leverkusen then Munich can occupy the top spot in the table. But I don't think Leverkusen will lose this match. Leverkusen are in very good form right now. And the important thing is that the match is Leverkusen's home match.
Leverkusen's players are able to score a lot of goals, as well as the team's defense is very strong. This team conceded only 14 goals in 20 matches. So it is a tough task for Munich to get 3 points against Leverkusen in an away match.
In their first meeting this season, Leverkusen and Munich only shared points and the result was a draw, so next week's meeting will of course be their second meeting and will determine which of the two is the best because they both need a win to take first place at the top of the standings, it's clear This is a tough job for Munich and Leverkusen, especially if you look at the performance statistics, both of them are in good condition, so the meeting between the two will be even more fierce, Xabi Alonso may have learned a lot from the results of the previous meeting so there may be a change in the strategy used in facing Munich.
I am also sure that Tuchel will do the same thing in order to win for Munich to get the full three points of course he will pressure his team to play optimally even though Leverkusen's defense line is quite strong, of course the strategy used must be better than the previous meeting and rotate players in next week's important meeting between Leverkusen and Munich, I don't think that either of them will win this match because both of them are equally strong so the result is likely to be a draw but both of them will probably score goals.
