Yes, Bayern Munich, Leverkusen, and Dortmund are the teams with great squads. I can say they will be the next season's Bundesliga trophy contenders, but the main two favorite teams to win it should be Bayern Munich and Leverkusen. Despite many people not having confidence in Kompany due to his past records, I have some confidence in him. I believe he can do great work at Bayern Munich and could win the Bundesliga trophy with the help of the great squad he has at his side. In fact, Bayern Munich is my favorite team to win the Bundesliga trophy next season because of the great players they have.But let's see what will happen as the season is about to start; maybe Leverkusen will surprise us again and win the Bundesliga.
Now, at least with the return of hope in the competition for the trophy of course this makes the Bundesliga more alive because in addition to the 3 clubs you mentioned of course we cannot forget Leipzig who can always be a stumbling block for competition or at least in the race for a position in the top 4 and some other surprise clubs like VfB last season although the performance of surprise clubs like this is difficult to predict.
4 Bundesliga subscription clubs Bayern, Dortmund, Leverkusen and Leipzig will be quite interesting to watch them in the race for the trophy later especially next season will be a new situation where their current coaches are still very young and of course they also have the capability as a coach because they certainly understand after they have previously been a player in their football career so this competition will be more interesting I think in the coming season.
