It was unusual in the Bundesliga when Bayern Leverkusen won the tittle under Xabi Alonzo this don't regularly happened in the Bundesliga as Bayern Munich is the team that always dominate the league. I believe that nothing is impossible it could be that another team will take over from Bayern Munich this season to win the tittle if this happens it means that the Bundesliga teams are coming to challenge Bayern Munich not to be the only team dominating the game.
Leverkusen not only won the title that season, but also dominated the league. They won the Bundesliga title by 17 points with a total of 90 points. But the next season they lost that dominance and Bayern Munich regained their lost dominance. That was the only exception in the last 10 seasons where we have seen a different team win the title.
The upcoming season may not be any different. Dortmund are still in the player business as usual, they never try to win the title. They value money more than achievements. If Dortmund ever build a team with the goal of winning the title and keep their star players regularly, they might be able to break Bayern Munich's dominance. Moreover, no other club in the Bundesliga has the financial capacity to build a deep team.
Xabi Alonzo made history in Bayern Leverkusen, they made the Bundesliga look differently in 2023-2024 season and that was Bayern Leverkusen first Bundesliga tittle, not only winning it in the first time they also played unbeaten, undefeated through out the campaign with just 6 draw games and 28 games win, Xabi Alonzo deserve some respect.
Dortmund is one team in Bundesliga that do challenge Bayern Munich but what Bayern Munich does is buy any of Dortmund best player to there team to make them stronger so they can continue to dominate the league, i think Borussia Dortmund prefer doing business than winning the Bundesliga tittle.
