Bayern Munich is indeed at a much better level, and they also have a number of players capable of making the league even more competitive, making it difficult for other teams to break their dominance. The quality of the players Bayern Munich has is above average compared to other clubs, making Bayern Munich the only one with a strong squad. It's hard to understand why Leverkusen chose Ten Hag as Xabi Alonso's replacement, given that they saw Ten Hag's abilities during his time as Manchester United manager. It was a bad decision for Leverkusen, although they have now ended their partnership with the coach, and we hope the new manager will be much more successful.
If Leverkusen had not immediately chosen Ten Hag as their manager and instead chosen another coach before the season started, perhaps Leverkusen wouldn't be experiencing the same predicament as they are now. However, I am more confident that Leverkusen will gradually improve, even though no new manager has arrived to replace Ten Hag. In this case, it will certainly be impossible to compete with Bayern Munich, let alone surpass them and break their dominance in the Bundesliga this season.
Looking back, before Leverkusen decided to bring in ETH, they first targeted a young Spanish coach who had a coaching style and vision similar to that of their previous coach, Xabi Alonso. They approached Cesc Fabregas, who turned down the offer and chose to stay with Como FC, the team he had just built. With no other options available, they ultimately appointed ETH as their new coach. Leverkusen recruited ETH not because of his journey in the English Premier League with Manchester United, but because of how ETH was able to lead Ajax Amsterdam to its heyday in the Eredivisie. However, in reality, it was a wrong decision, which led them to the current precarious situation where they had to replace the coach when the season had just begun. Initially, they considered Spanish coach Xavi, the former FC Barcelona manager, but unfortunately, Xavi outright rejected the offer. However, the Leverkusen coaching position is no longer vacant, as Hjulmand has been appointed as their new coach, and hopefully, he can bring about changes and reignite the players' spirit.
