The real challenge for Kompany will come soon when Leverkusen and other teams understand the strategy Kompany uses in Bayern Munich which can make Xabi Alonso understand the weaknesses and the way they can win against Kompany and his partner. However, so far Kompany had an epic performance in the Bundesliga but I don't think if this will continue for a long time regardless of the players and potential they have in Bayern Munich. In my own idea still, Leverkusen can have a much better chance than Bayern Munich.
Whatever happens, I do not have any thoughts at this time if Leverkusen can replace Munich's position again even though Alonso already knows the strategy used by Kompany, but every coach has always has another strategy option and has a lot of tactics. So that Kompany is also very worthy to be able to see the weaknesses of Alonso's strategy.
Before Leverkusen shifted Munich's position with a large difference in points, I still believe Munich would remain a leader in the standings at the end of the season.
The Bundesliga has only been running for 5 weeks, and there are 29 more weeks to go, it is difficult to predict who will be at the top of the standings at the end of the season. The challenges that the title challengers will face this season will be more complex, where the addition of European matches will be one of the influencing factors, apart from their respective competitors at the domestic level. Bayern Munchen and Leverkusen are the main competitors in the fight for the trophy, we all probably agree on that, but the potential of Dortmund, Leipzig cannot be ignored, as well as Eintracht Frankfurt.
Stuttgart, who is currently a little unstable, also has the potential to rise again to enliven the top four of the standings, so that it will make the competition even fiercer. I think the competition for the trophy this season will involve several teams at once, not just Bayern Munchen and Leverkusen. This is certainly very good for increasing the competitive level of the Bundesliga, so that it attracts more interest from football fans.
