I don't think if leverkusen will lose 4 straight matches, considering their 9 up coming matches I think Frankfurt, dortmund, freiburg, stuttgart,this above mentioned club is considered been a threat to leverkusen. but I'm pretty sure that if leverkusen is going to lose I think it will only be 2of their matches, which is either to dortmund or freiburg,I don't consider the rest as threat to leverkusen instead of this teams to win leverkusen they will make it draw.
I don't think there will be many draws in this match; most of them will be in favour of Bayern Leverkusen because they no longer appear to be scared after beating top teams like Bayern Munich in the league to maintain their current position. When playing against them, these teams may be afraid of losing to them because they have been on a winning streak. With the remaining fixtures, I don't believe Bayern Leverkusen's position will be endangered. They appear to be in complete control and on track to win their first Bundesliga title.
