I also thought like that but it seems we were wrong about Leverkusen and they continued to progress without ever tasting victory. But at the moment there are still a few matches left and if we talk about the next match against Stuttgart, I think Leverkusen can still overcome this. The reason is that in the first meeting at the start of the season, Leverkusen did have difficulty facing Stuttgart but they were able to stage a comeback win in the 90th minute and that was enough proof of how their mentality works.
Leverkusen always refused to lose, there were many matches they scored a goal near minutes 90 or injury time.
Yeah the upcoming match against Stuttgart will be interesting to watch, this season both Leverkusen and Stuttgart have improved a lot among other teams in Bundesliga. I think it will end in draw, but I won't really surprised if Leverkusen lose in this match.
Indeed, sometimes I also think the time will come for Bayer Leverkusen to lose the remaining matches this season. But playing against Stuttgart in the next Bundesliga match, it turns out that Bayer Leverkusen will also be playing at home and itseems difficult to beat Bayer Leverkusen at home.Moreover, in the previous match Stuttgart also lost by Werder Bremen and Stuttgart played away. With results like that, although I also admit that Stuttgart has good abilities to be able to provide tough resistance to Bayer Leverkusen, but still, beating Bayer Leverkusen at home is a difficult task for Stuttgart. But yes, any result is still possible, but it looks like Bayer Leverkusen is still able to maintain its consistency so as not to lose in the home match against Stuttgart later.
