Dortmund can find this chance like once in ten years or so as of now. But they messed it up anyway and handed the Bundesliga title over to Bayern Munich. As I believe that Bayern Munich are likely to start recovering and being a more consistent team again with Tuchel, Dortmund's job is harder. However I think that they don't care about how many times they win this title as it isn't the priority.
We will continue to watch Dortmund concentrating on their main goal as usual which is to grow new talents such as Bellingham, Haaland and so on. By saying "to grow" of course I don't mean only their youth setup. They have really good scouts and they should be able to find new big talents at young age.
Some blame rests on Dortmund's fans as they appear calmer compared to supporters of other clubs. The club is expected to provide stiff competition against Bayern Munich, but unfortunately, they have been unable to fulfill that expectation. Retaining talented players who have grown with the club would be beneficial for their progress. Regrettably, Dortmund has a tendency to sell players in search of monetary gains. This constant selling hinders the development of trust between the players and the club regarding their future prospects. Consequently, players start exploring better opportunities elsewhere. To be honest, my hope for Dortmund faded after last season.
