Although munich currently have a 4 point advantage over leverkusen but still they are still not safe in the current standings, leverkusen still show good fight mentality this season although not as great as last season in dominating the league, so I think their chances of remaining a title contender this season are very open, against dortmund will provide an opportunity for them to shorten the distance from munich, although indeed dortmund been able to dominate over leverkusen, but dortmund poor performance this season should be able to take advantage of them to get 3 points in the match later, especially there is a possibility for munchen to lose points when facing gladbach in another match, so far gladbach is not a big and strong team in the bundesliga, but they has become the most difficult opponent for munich so far, even often gladbach has become a nightmare for munchen every time they meet.
At the beginning of this season, we saw Leverkusen's inconsistent performance. We thought that Leverkusen might not be able to compete for the title this season. But gradually we can see Bayer Leverkusen's improvement. With the help of Xabi Alonso, Leverkusen is now quite strong. And now the team is competing for the title.
Bayern Munich is performing well this season. There is no doubt that Bayern Munich is the favorite to win the title. However, if they cannot perform well consistently, Bayern Munich will not be able to maintain the top spot in the points table. Bayern Munich is 4 points ahead of Leverkusen. This is not a big gap. So Bayern Munich will have to try to continue their good performance consistently.
