Bayern Munich will always be the favorite of winning the Bundesliga every season. Dortmund always sell many of there key players to other club, and that is why they usually strongly at the ends to win trophies every season. The more you sell key players in your team you need to replace them more with others. but Dortmund don't usually do so they buy small players to build up. and if you Don't have a better coach that can build players they will always suffer at the ends. Leverkusen as be in a better form and Erik Ten Hag just need to maintain the performance. But if he fail the club will go back to day one strongly again. Let see how the season will be. because every season we usually see some challenges and see small other clubs improve more better and challenges the big club to achieve the league title.
Because Bayern Munich was successful in winning the Bundesliga last season does not mean that they are the favorite to win every season; even last season, it was just that the Leverkusen performances were somehowlow right from the beginning of the season. If not, I don’t think that Bayern Munich could have found it easy to win last season.
That’s just the main problem of Dortmund selling their best players, which is what weakens their performances, and instead of them giving out their key players to the other clubs, the best thing for them is to sign more players that can work harder than those that they sold earlier, but they won’t, and that’s why they end every season without dominating the trophy.
