Xabi Alonso's men has been playing really well in recent times. If you see the last match, they have played like they were the best team in the Bundesliga. Schick has played extra ordinary in that match. He alone scored 5 goals 
. Die Werkself dominated the whole match, they had 67% possession in this match, 20 shots, and 12 of them were on target. This was a greatly one-sided match and I did not expect this match to be so one-sided. Looking at performances like these I agree with you that they are definitely going to give Bayern Munich a lot of problems. We, or at least I thought that Bayern is going to have an easy time this season. But It seems like this is not right. If Bayern makes any slip-up Leverkusen will be there to take advantage of that. And this alone is going to keep both the teams honest.
not surprised actually if the match will end with a big win for Leverkusen. Freiburg was also defeated by Dortmund with a score of 4-0 and now they have to lose 5-1 to Leverkusen. Leverkusen has the spirit to continue winning matches in the future. they are chasing Munich who has a points difference in the competition. so Leverkusen must not lose points if they want to catch up with Munich..

Only half of the season has passed and if Liverkusen remain stable, then we can start to think that it is dangerous for Bayern, but now I agree with you that they are very far from the first place, Bayer play a lot of draws.
Leverkusen may not have performed as well as we expected at the beginning of the season, but now they have become a consistent performer again.
A few matches with Bayarn Munich, Leverkusen had a considerable point gap, but that point gap is slowly decreasing. On the one hand, the decrease in points gap with Leverkusen is good news for Leverkusen fans, on the other hand, this news is not happy at all for Bayarn Munich fans. If Bayarn Munich performs badly in the next few matches, on the other hand, if Leverkusen performs poorly, it will be seen that Bayarn Munich is falling behind Leverkusen. But I expect Bayern Munich to win the German league title this season.
