The next round will be decisive for the whole season, if Bayern's winning streak continues, then it is unlikely that we will have any more intrigue. I don't know if it's good or bad that Bayer and Bayern are meeting in the 5th round, but considering that Bayer has already lost 3 points, they have no right to lose if they want to stay in the race. Naturally, bookmakers see Bayern as the clear favourite:
1.73 - 4.30 - 4.20
I hope everything will happen like last season when Bayern were the favorites but lost 0-3

Leverkusen is not playing close to its performance last year. They suffered their first defeat against Leipzig. In the Bayern match, they will be playing away and their form has dropped. Moreover, Bayern is in very good shape. They are very efficient in goal. When we put these together, we understand once again why Bayern is the favorite. Bayern can win the match and leave Leverkusen behind for the championship. Therefore, I am sure they will prepare very well for the match.
Is Bayer really that bad? Their only problem that can't be denied is that they concede a lot of goals. Otherwise, they have kept the same will they had last season and one defeat doesn't change anything (or did you expect their unbeaten streak to be endless?).
Now the question is: are Bayern really that good? Yes, they scored 29 goals in 6 games, but who were their opponents? Ulm, Wolves, Freiburg, Holstein, Dynamo, Werder. Not a particularly impressive list, right? And Bayern conceded 2 goals from Dynamo at home. The game against Bayer will be their first serious game of the season.
