Borussia Dortmund use to be very consistent on there Bundesliga then but now a lot of things has changed about them, though Borussia Dortmund is well known in terms of generating a good players because the above listed names are currently doing very well on there current clubs.
Ever since I knew the Bundesliga, Dortmund has always been able to produce great players who go to big teams. In fact, they don't seem to have any intention of winning the league because they always sell their best players. But it seems that Dortmund has become a business-oriented club. As long as they are not bad in the League and have an advantage then they will not be a problem. It seems that supporters are also not too fanatical about the champion.
The Dortmund team has no interest in winning the Bundesliga title. If they wanted to be champions they would have strengthened their squad more. But Dortmund have never spent huge amounts of money to strengthen their squad. Instead, Dortmund sold the best player in their squad and made a huge amount of money. Dortmund sell the best players in the squad almost every year.
If Lewandowski, Bellingham and Haaland were in Dortmund's attack, this team would undoubtedly become one of the strongest squads in the Bundesliga. Dortmund management has found many such talented players. But their main business was to make money by selling players. This is why despite the talent and potential of the Dortmund team, the team cannot dominate the Bundesliga.
