If Leverkusen can be able to hold on and get a point against Munich, then they can go the complete season unbeaten, and their chance of winning of getting point against Bayern Munich is high because they collected four points against Bayern Munich last season.
If next week when Bayern Leverkusen play at home to host Bayern Munich win. maybe the German Bundesliga championship race is over. most likely Leverkusen can win it even though they can't lock the championship because there are still many matches. but it can be said that the mentality will rise dramatically. while Munich mentally will drop in addition to the point difference also being away.
Currently Leverkusen and Bayern are only 2 points apart and in my opinion whatever the result of this match will not affect the competition between the two teams in the race for the title.
There are still a lot of matches remaining this season and it is not easy for the team to maintain its consistency.
In my opinion, the competition will continue until the end of the season and in this weekend's match I don't think Bayern will lose even though they will be playing at home to Leverkusen, but Bayern will definitely use all their strength to be able to win points in this match.
I think a draw is likely to happen.
