Even when people were saying Bayer Leverkusen was not going to get to the top of the table this season, I was just looking, because when the season started, Bayer Leverkusen's performance was not as good as it is now, and everyone was saying they would experience a hard time this season. However, currently Bayer Leverkusen has already taken over the second spot of the table, which is going to be another pressure for Bayern Munich right now. Bayern Munich needs to work smart and win their matches because Bayer Leverkusen is already close to them.
It is the fact that Bayer Leverkusen is experiencing harder season, they didn't perform as well as in the past season. It was not surprising if people claimed they may not win the title again, Leverkusen missed many points in the early of this season. However, they are improving their performance recently, they have the chance to return in the top standings. Yep, they are in the 2nd place already, it is surely a big pressure for Bayern Munich. Now, we can assume that Leverkusen is in the title race anymore.
4 points is not a big difference, and since Bayer Leverkusen's performance is strong and their performance is back, seriously, they can get this point and get to the first place in the table. They will be playing with Dortmund in the next coming days. Let's see what will happen then. I think from there we are going to know how strong Bayer Leverkusen is.
Indeed, Bayern Munich and Leverkusen have no big difference point gap. If Leverkusen can keep winning the matches (including the match against Dortmund), Leverkusen has the opportunity to overtake Bayern Munich in the 1st place. I really expect that Leverkusen can steal full points in Dortmund home, it will be a crucial point for Leverkusen.
