Yes, it true that Leverkusen currently seems to be a substitute for Dortmund last season because currently Leverkusen, after being coached by Xabi Alonso, this club has made huge improvements, even being able to beat big clubs or draw with other big club, but it doesn't rule out the possibility that Leverkusen will become a challenger. which is strong because it could surprisingly increase the performance of its players so that it can make competition even stronger and Bayern Munich has to work hard if it has to challenge 2 big clubs at once and apart from that, Leipzig also currently I admit has a big opportunity to disrupt Bayern Munich to get a position top again.
It a little thought that I sometimes think that Leverkusen also seems worthy of getting the Bundesliga title because they have previously won the title in this Bundesliga.
I think there is a difference between Leverkusen and Dortmund. Last season, Dortmund was not much like the start of this season, they experienced problems with their performance. plus, due to the illness of their striker Sebastien Haller who had to be absent for half the season. In the second half of the season, Dortmund performed brilliantly with a positive trend, until the competition for the trophy between Bayern and Dortmund was determined in the final seconds of the Bundesliga match schedule.
The difference with Leverkusen is that at the start of this season they played their matches with a positive trend. Of his 6 matches, he only experienced 1 draw. that too, during the match against Bayern Munich. the rest, they achieved with big wins. However, there is nothing wrong with what you said. If last season Dortmund was Bayern's strongest competitor, this season it looks like Leverkusen will be one of the contenders for the Bundesliga title.
For me, we can't confirm the consistency of Leverkusen or Leipzig. Remember, this competition has only been held for 6 matches. There are still many games left until the end of this season. If, Alonso is able to bring his squad to remain in an injury-free condition and remain in top condition. they have a chance to break Bayern Munich's dominance. However, it looks like it won't be that easy. if Neuer does not recover in the near future, Tuchel will bring in the ideal goalkeeper. plus, several newcomers to their defensive line. which means, the course of this competition is still difficult for us to predict. There's only one thing we can do, enjoy every match the Bundesliga presents.
