Borussia Dortmund is known to be selling their best players in almost all the summer transfer windows and that is why Bayern Munich will continue to dominate the German Bundesliga for more seasons to come.
Jadon Sancho was sold last two summer before Erling Haaland was sold to Manchester City last summer and now Jude Bellingham has left for Real Madrid. I think the club's transfer strategy isn't concerned by the success of the team rather they're more concerned by how much they make as gains when they sell these players. They might also be lucky raise another great player before the end of next season and still sell him at the end of the season

If they were able to retain the good players, Bayern could not have been dominating the league for years. It takes a consistent team to have great success, it's only financially good to sell a player who can make money without using it to another team.
On the one hand, they are doing something quite logical, they always sell their players when they are at their most valuable and make a lot of money. But their chances of becoming champions are dwindling
It takes a consistent to achieve success and if the club's management doesn't stop that their traditional transfer policy, it simply means they're more concerned with how much the club makes from those transfers instead of helping the club win major football honours
There is no reason for Borussia Dortmund to be able to thwart Bayern Munich's dominance, while Dortmund last season sold their best players and this is Dortmund's mistake in not being able to take the opportunity in their last game against Mainz which could give pride of being the Bundesliga champion last season but failed because of a draw.
