A lot of people really didn’t think Bayern Leverkusen would be able to perform this well because of how they started the season it was really kind of disappointing but funny enough they didn’t lose a lot of matches they just draw a lot of matches and lost points in the process but then they were still able to bounce back after the set backs.
To be honest , against the last year and how they played and performed they are really bad when it comes to win the there games.
But the other teams maybe have done there homework and they know what is coming from Leverkusen when they play against them.
So i guess that it is normal that Leverkusen is not going through the league as they have done last season.
4 points is not that big and can be caught up in just 2 games.
