But that is difficult to happen because Dortmund continues to sell their best players in every transfer window. In fact, they don't regret their decision because they were really looking for money in the transfer window. Like selling Bellingham to Real Madrid, of course many people consider it a big loss for Dortmund to let go of their best star. But they only focus on looking for big profits in every transfer window so it's not surprising that Dortmund has been fasting for a title for a long time.
Even this season, players who stand out at their club could be released in the winter transfer window because Dortmund don't think about anything else other than making money in the transfer window. This season, Dortmund is not too strong in the Bundesliga because other teams are able to perform better than them, such as Leverkusen and Bayern Munich. I think Dortmund still maintains their trend of only being in the top 4 every season.
They were almost close to winning the league last season but since they decided to sell Jude Bellingham to Realmadrid i don't think they'll get that close again this season, people may consider it a big lose but they didn't lose totally, they gained about a €100m plus for the sale of Jude Bellingham and would use money from there to get youngsters that would replace Jude and that's how it's been going on.
Selling the best performing players every season has come normal in the club and with time it would turn into a tradition, well i don't think they'll stop because it's not affect their top 4 goals, they'll still struggle and manage to finish in the top four this season, sell one or two rising stars and get another ones, all thanks to their scouting network that help them recruit young talented players around the globe.
