This time looks like Bayern Munchen have a very staunch contender for the title which is Bayer Leverkussen.They are winning every single game and the only draw they have is against Bayern Munchen at Bayern Munchen home,this should be a bell of alarm for Bayern Munchen as they won't have it that easy to win the title this year,nor that they had easy last year when Dortmund fatally lost it in the last game of the season by drawing at home against Mainz.This time though is not Dortmund,it is Leverkussen and I highly doubt if they were to be in the same situation as Dortmund last season they will fail to achieve the title.
What Leverkusen needs to ensure the title is consistency. At the moment it could be said that this is their best performance at the start of the season. Actually, I also want a new champion in the Bundesliga. Dortmund failed in several seasons because they were inconsistent when entering the middle and end of the season. It's still very early to determine how Laverkusen will move forward. I will wait until half the season is over and what ranking Leverkusen will be at then.
I agree with you that consistency is something Leverkusen must have if they want a Bundesliga title this season, especially since it's only Week 7 and they still have a long way to go to get closer to the championship. Sometimes teams can be consistent until halfway through the season, but in the second round they lose it and in the end it must make them fail to become champions. Now they have a good game, their attack line is reliable, their defense is also working well. All they have to do now is maintain what they've shown so far and also improve their performance.
