This should be a sign for Bayern that this season they cannot relax like previous seasons because indeed the clubs in the Bundesliga are now increasing in quality which makes it difficult for us to predict what happens in 90 minutes of the match.
Exactly, Bayern Munich has a big challenge this season that cannot be underestimated. Leverkusen and Dortmund, at least those two clubs will be their tough competitors.Especially if we look at the last match Bayern Munich vs Wolfsburg, even though they won, their game was not effective and accurate enough.
Check these statistics:

They have 71% ball possession, but only 8 shots on target, and only 2 goals created + 1 OG
However, Bayern Munich have made a great start to the season and their style of play has been excellent. A great win at the start of the season which gave Bayern Munich more confidence, and they will play harder in the next matches. But it must be admitted that the biggest challenge for Bayern Munich is that they have to compete with the two teams Leverkusen and Dortmund. Bayern Munich didn't attack at all with the way they played the opening match of the season, and if they deal with that, they will certainly face challenging ones later on. So I think that since the coming matches will be more challenging, Bayern Munich will have to improve their game even more.
