This plan looks set to continue. Borussia Dortmund has been following this strategy for a long time. They are making a serious profit. They do not want to give up this gain. They wouldn't have sent Bellingham if the Bundesliga title had been their goal.
The business that has been run by Borussia Dortmund for a long time is still proving to be very effective now by continuing to make money through their players, but in terms of the Bundesliga title I think Borussia Dortmund is also still thinking about it because last season Borussia Dortmund seemed to be competing with Bayern Munich in the standings until end of season. This indicates that Borussia Dortmund still has the desire to become champions in the Bundesliga even though they have not stopped running the business they have been doing for a long time.
