I actually want to believe that Bayern Munich knew it much earlier before now that they are going to have Leverkusen as their biggest rival and contender for the trophy this season so making sure they are going to be able to stay ahead of them was one thing that was supposed and going to be their priority this season and now the the distance has been closed to the point is just four point difference is some how disturbing but then Munich still have the chance to still staying ahead.
I think that for Bayern it all comes down not to the confrontation with Bayer, but to the task of winning the Bundesliga, and despite the fact that Bayer is now the closest pursuer of Bayern and they have a very good winning streak, I do not think that Bayer has a great chance to defend the champion's title. It will not be easy for Kompany to confront Alonso, because given the victory last season, Alonso has more experience.
It does not matter who the rival team will be whether Bayer Leverkusen or Dortmund or other teams because anyway, to get trophy then of course Bayern Munich must again have great dominance in Bundesliga. After all, last season chaos was also due to perhaps the factor of the coach and perhaps also, the factor of the absence of good chemistry in the team, so Bayern Munich experienced chaos last season. This season, Bayern Munich again managed to have good results, if this season Bayern Munich's performance has not improved then it is very likely that there will be many teams that are able to compete for trophies. Thus, the way to remain a major candidate for the trophy, of course, is to maintain consistency in every match with good results, because other teams are also making great efforts to reach the top.
