Leverkusen's chances of winning the Bundesliga for the first time this season are very big. It's true that the season is still long, there are still many matches, anything can happen, you never know what will happen in the future. However, Leverkusen has good capital to win this match because so far they are unbeaten in the Bundesliga, and Leverkusen is playing at home.
I am thinking that Xavi Alonso will do the same as Arsenal Wenger did in the year 2003/2004 season where Arsenal go all 38 matches unbeaten. This is. Possible for Bayern Leverkusen this season because they are very consistent and are not given Bayern Munich any space to come close to them; Bayern wanted to come close after Leverkusen drew their match against Gladbach, but they win their last match against SV Darmstadt who are now at the bottom of the Bundestag table to make themselves two points clearer ahead of Bayern Munich.
So in my opinion the match against Bayern Munich can be said to be a decisive match, it will be very interesting to watch because this match is also a match to show the true performance of both teams, and of course get three points to reduce the opponent's mentality.
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.
