Dortmund have slowed down a little about their young player transfers these days. They have brought amazing names to the team so far such as Haaland and Bellingham. Their total profit in the sales of these two players was really good. There are a lot of talented players in the pool right now surely. Dortmund just don't want to rush anything for now.
The money that raised from selling haaland and bellingham being used to paid its expenses. The profit can be considered as good enough but it's not as big as you said. It's been reported by dortmund's financial report.
Dortmund is trying to hunt another young talented player to be developed again. I think that you will be seeing some names to join in the dortmund soon. Some names being targeted by the club this time.
Maybe a central midfielder transfer would be really good for Dortmund. Because it was Bellingham's main position and now there isn't anyone there whose position is that naturally. They can surely look for a big talent like Bellingham for this position.
Dortmund has signed felix nmecha as a replacement for bellingham. You shall not feel worry as dortmund was aware if the club shall get a new midfielder to replace bellingham as soon as possible.
The clubs is very fast in getting the new talent. I really appreciated how good the talent recruitment that owned by dortmund.
