With the current performance of Bayern Leverkusen I have a great confidence that they will surely win the league because they have shown themselves worthy to become the Bundesliga league 1 champion, however Bayern Munich have been there only nightmare because Bayern Munich is looking for every opportunity to bring them down from the first position of the league but could not, do to how strong in performance Bayern Leverkusen is and also there consistency on this season league is something to write home about because they have actually proven to Bayern Munich that they have the performance that cannot be stop by them.
However Bayern Leverkusen is leading with 42 points while Bayern Munich is currently 38 points and however the Bayern Leverkusen upcoming matches is a very sure win match for them because there performance is far better than those clubs and at the same time making Bayern Munich chances of entering the first position very impossible for them.
They did provide a great sight so far, but that doesn't mean that they will win, it is not going to be easy for them to get that title, and it would not be simple for any team to fight against someone like Bayern.
But Bayern in any league and you will have some trouble, which I would assume would not be easy, you can put them at Premier league and they would still fight for the top, not saying they would get it, but they would be somewhere near the top, same goes for serie A, la liga, ligue 1 and everything else. I am not saying they would win them all, but they would be one of the best teams in all of them. So Bundesliga is hard to win when Bayern is there, we don't know what will happen but it will definitely be tough.
Bayer Leverkusen will have to prove that they can win the Bundesliga title to actually make people believe. Because we have seen a lot of things that have been unbelievable but true. Since the last 11 years, a lot of teams, especially Dortmund had very good chances to beat Bayern Munich for the Bundesliga title. Even after getting so many good chances, Bayern Munich has been able to win the Bundesliga title for 11 years straight. So even though they have four points advantage, they will have to remember that they have also played one match more compared to Bayern Munich. So they will have to keep in mind that the point difference can decrease very quickly.
