Dortmund performed well last season. Unfortunately, the team failed to win the title. However, their performance in the last season has seen the Dortmund team capable of breaking Bayern Munich's dominance in the Bundesliga. And this is why Dortmund will probably target the title next season.
Dortmund has an excellent attacking division based on youth. I would say almost all offensive players are talented. But Dortmund need at least one experienced striker if they want to win the title. If Dortmund spend some money and adds an experienced striker to the squad I believe they will be able to challenge Munich for the title next season.
Dortmund failed to break Bayern's dominance, you wanted to say that they had a great chance to do it, but they themselves could not do it despite the fact that everything was completely in their hands. Bayern ended the championship very poorly, the team spirit was at a very low level, but even this did not prevent them from becoming champions again, so everything remains the same, despite everything, Bayern continues to dominate the Bundesliga.
