Actually, Leverkusen performance this season hasn't been too bad, they are still considered successful in the context of making the Bundesliga trophy rice competition remain competitive, so it's not easy for Bayern Munich to dominate again. Repeating the success of last season is very difficult, as it requires a lot of luck. Regarding Leverkusen chances of defending the trophy, I think the chances are still open, it's still possible to close the 6-point gap. That's right, we also shouldn't say too early that Bayern Munich will win it this season, because there's still a possibility that the situation could change in the remaining 6 matches.
I don't agree with you. Leverkusen needed to perform better if they wanted to win the Bundesliga. Last season we saw Leverkusen play great. Bayern Munich never had a chance to compete for the title. This season Leverkusen's performance has been quite inconsistent. That's why Munich is at the top of the table.
I wouldn't say Munich is playing very well. If Leverkusen could have performed more consistently, they could have kept the top of the table. Leverkusen have drawn 8 matches and lost 2. They lost to a weak team like Werder Bremen a few weeks ago. After Leverkusen lost this match, I gave up hope for Leverkusen to win the title.
