It's difficult for Leverkusen because in the end there are only 2 options for the Bundesliga when it comes to trophies, one is Bayern and the other is hoping Bayern play very badly and other clubs can compete for the championship but for this season I doubt Bayern will play badly (like last season).
Bayer Leverkusen made a great start to the league. Their only point loss was a draw against Bayern Munich. Since that game was away, it can still be considered a great success. Boniface, who scored 7 goals in the league, along with Hofmann, Frimpong, Wirtz and Adli are terrorizing all teams. When you play so effectively on offense, things are easier.
Xabi Alonso wants to prove himself as a young coach and has made a very good start to his managerial career. Such young managers usually have a positive impact on teams. Bayer Leverkusen showed that they made the right choice.
I don't know how long they will stay at the top of the league, but they have already shown that they are a serious threat to Bayern München. This season the league looks like it will be more competitive and exciting.
I just don't understand that there are still people who doubt Bayer Leverkusen even though indeed, Bayer Leverkusen also still cannot fully guarantee to stay at the top of the Bundesliga standings until the end of the season. But anyway, because Bayer Leverkusen has managed to have good results from last season until now, then at least the doubts about Bayer Leverkusen maybe a little lost. Because with good performance and stable results also so far this season, then I personally will not doubt Bayer Leverkusen this season, because of course Bayer Leverkusen has a very good chance to be able to compete in the Bundesliga title race this season.
