But if anyone is saying that Brussia Dortmund is better than Bayer Leverkusen such a person is absolutely not making a wrong claims. The only arguments you guys are making here in favour of Bayer Leverkusen is their last season's unbeaten campaign which culminated to their winning the Bundlesliga title whereas Brussia Dortmund has consistently been in a top outstanding form in all seasons for the past one decade both in the Bundlesliga and champions league competition's.
For this current season we don't know for sure how far Bayer Leverkusen will go in maintaining their performance especially in the champions league and even in the Bundesliga but am quite sure that Brussia Dortmund as usual will make it far than Xabi Alonso and his boys this time in all competition's.
I don't see much chance for Leverkusen to win the title this season. This team did great last season and they went undefeated to win the local league title but this season is definitely tough for them. Bayern Munich have played two matches so far this season where they have earned full points in both matches. Leverkusen, on the other hand, have played two matches but lost one, meaning they are currently 3 points behind Bayern Munich. If we compare the performance of Leverkusen with Dortmund then we must put Bayern Munich ahead in the performance of the first two matches because they have not lost any of the two matches, they have won one match and they have drawn one match.
Whether Leverkusen will win the Bundesliga title is not possible so quickly. Bayern Munich have won their first two matches. However, Munich's performance in the first match against Wolfsburg was not good. Several weaknesses in Munich's squad are still quite visible. Leverkusen, on the other hand, lost against Leipzig. However, the teams have barely played two matches each. There is still a long journey ahead. Therefore, it is not yet possible to say for sure which team will be the Bundesliga champions.
I think if Kompany's target is just to dominate the Bundesliga then maybe Munich can win the Bundesliga title. However, if the KOmpany tries to dominate the Champions League and Bundesliga at the same time, it will be difficult for Munich to maintain the consistency of good performances.
When talking of the German bundesliga, I also share the same sentiment as you bro, we are still in the early days of the season, and it's just two matches played, we haven't seen the best and the worst of all this top teams, I believe that by December the picture will be much more clearer, and by then the real competitors might have emerge, but as for now, am seeing a little bit of promises from this Bayern Munich side, even though they are not at their best, but their is much more improvement from the way they were last season, then as Bayern Leverkusen, though they have lost a game this season but that doesn't define if they are going to be challenging for the title or not, so by December hopefully, the picture will be much clearer.
Then as for your last paragraph, I believe that if Bayern Munich are actually good, they can compete on both front, I mean the German bundesliga and the uefa champions league, because they aren't new to such a situation, they have been able to compete on both front while dominating the German bundesliga over the years, so their is nothing new about it.
