Yes, Bayer Leverkusen still looks strong at the top of the Bundesliga standings, even when Bayer Leverkusen achieved a draw with Dortmund, Munich was unable to take advantage of the opportunities that existed against weak teams instead they suffered defeat and as a result were unable to shift Bayer Leverkusen's position so Bayer Leverkusen still sits comfortably at the top of the standings with a difference of four points from Munich. Knowing this, Munich is definitely very under pressure with the presence of Bayer Leverkusen which makes it a little difficult for them to win the title again, but according to some people this is what is expected because there is another team that dares to break Munich's dominance in the Bundesliga and this makes the league more competitive and not boring.
We will never know how long Leverkusen will be able to maintain the consistency of their team's play, but what is certain is that Leverkusen's presence or strength this season makes the Bundesliga competition even more interesting with the threat that Bayern will no longer be able to defend the Bundesliga championship title that they have controlled for so long.
Personally, I hope that Leverkusen is able to win the Bundesliga title this season and I am sure that this will make the Bayern team improve even stronger and that will have a positive impact on other Bundesliga teams in the future to be even better.
