Even without Robert Lewandowski and Manuel Neuer, I believe Bayern Munich is still a very strong team and probably stronger than the others in the Bundesliga. So I do not think that they should be struggling. Especially because they have so much money that they can already fill up that void.
In the last season, the team which have the potential to beat them was Dortmund and Dortmund also came really close. I wonder if that is going to happen any time soon. I think in the next season Bayern Munich is going to be a lot more careful. They are going to bring in new players. Regardless to say that in the next season, Bayern Munich is going to be stronger.
Bayern Munich is still very strong despite the loss of Robert Lewandowski and Manuel Neuer, but their domination in the Bundesliga is no longer the same, moreover Thomas Tuchel is not so quick to integrate existing players so he needs adaptation next season. The arrival of several new players will help the team become better and we also know that Bayern Munich's finances are still quite strong compared to other teams in the Bundesliga.
Dortmund as Bayern Munich's strong challenger in the 2022-2023 season, actually had a great opportunity, but unfortunately they had to lose their chance in the last game and even that happened at home. So I believe that Bayern Munich's ability is still quite strong in the Bundesliga next season and it's just that they need to adapt.
