Koln against Bayern Munich and Werder against Leverkusen are both profitable for the visitors. So it's no surprise that Bayern Munich and Leverkusen can score full points in this match without having to worry at all. So Bayern Munich needs to be a little patient, the difference is 2 points. I don't see this match being a big problem for both of them, Werder performance during this season has been very chaotic from the last 5 matches with only one win, 2 losses and 2 draws, the same as Koln last 5 matches in the Bundesliga, one win, 2 draws and 2 losses. In other words, Bayern Munich and Leverkusen both benefit.
of course, as hosts, Leverkusen and Bayern Munich will be very lucky to be able to compete against weak teams who are at the bottom of the standings and of course all bettors will not hesitate to bet on the favorite team.
but you need to pay attention to the Bremen vs Leverkusen match and consider it to see that the match ends in a draw because from h2h history, although it is not very strong, Bremen has the opportunity to hold the match to a draw when playing at home.
meanwhile, Koln vs Bayern Munich in h2h history, Koln has beaten Munich 1x and drawn 1x and that means the chance of a draw is also possible in this match even though Munich is stronger in terms of player performance but remember the surprise will definitely come from a weak team.
TBH, I not consider h2h as a benchmark for predictions, but from my experience, sometimes weak teams can give unexpected surprises, such as ending in a draw, and I often experience this when betting on favorite teams and its better to bet with safer options.
