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.
Things that should have been favored by many people changed after the first round of the Bundesliga finished. Bayern Munich have recorded a bad record this season so they are 4 points behind their arch rival Leverkusen. The League still has a long way to go.
Bayern Munich has time to change the standings at the top so they can defending the title, we know this will not be easy for Bayern Munich but if they are consistent and compact in the game then it will be easy to catch Leverkusen even though Alonso has more experience but Bayern Munich is the best team that has entered the European record.
I don't believe Bayern Munich is performing poorly in the league, they just want to have issues in the Champions League. they are playing well in the Bundesliga, which is why they are still at the top of the league competition I don't think Leverkusen will win the Bundesliga this season they will only finish second in the league table. Kompany will continue to perform well in the league, and he will not try to perform poorly in order for Leverkusen to overtake them in the league table. Because Harry kane will do is best and achieve trophy because he as not won it before for is career so this is the best opportunity for them the achieve it this time. Xabi Alonso is a good coach, and if Munich does not improve very well, they can overtake them, and he can be a problem for them this season because they will not try to lose any points in the league anymore; instead, they will try to give Munich a big gap so Munich will not try to make a mistake and allow Leverkusen to overtake them in the league competition; let's see how the competition goes because they still have a long way to go, and we can't predict what will happen ahead.
