I doubt Xabi Alonso's Leverkusen can dominate the Bundesliga next season. Leverkusen cannot win the title by going undefeated for a whole season. If Leverkusen wants to dominate the Bundesliga next season, Leverkusen management should definitely try to strengthen their squad. We saw the Napoli team dominate the 2022-23 season and win the title. However, last season we saw this team finish tenth in the table. So Leverkusen will have to play very carefully from the start of the season if they want to win the title.
There won't be too many expectations from Bayern Munich next season. Bayern Munich have a strong squad but new coach Vincent Kompany is not experienced enough. I don't know why Bayern Munich have appointed such an inexperienced coach.
If we compare Napoli who were unable to win again in the following season, it was because the coach who led Napoli to victory decided to quit and leave. So Napoli have a new coach and the strategy they use is very different from the previous coach. Leverkusen still has a coach who succeeded in bringing them to victory so there is still potential to win again in the coming season. It is possible that Bayern Munich's performance has also weakened, so Leverkusen will take advantage of this moment to stay in top position.
Yes, it means that Leverkusen will still have the same chances next season if they are still under the care of Xabi Alonso, although no one knows for sure about what will happen next season but I think the achievements achieved by Leverkusen last season are really enough to be used as a benchmark for how their fate will be next season, meaning simply as long as they are taught by the same coach then most likely their chances next season will also be the same as last season.
On the other hand, as we know that Bayern Munich has a new coach after Tuchel left, Vincent Kompany, I don't really know how the coach's achievements in his career but I will simply say that he will certainly need time to adapt to Bayern Munich as his new squad, and indirectly this could be a moment or opportunity for Leverkusen.
