It looks like if Dortmund are able to retain their best players I think it will not be difficult for Dortmund to dominate matches in the Bundesliga but the question is whether Dortmund can retain their best players? while there are lots of rumors that Dortmund still want to sell their best players like Bellingham.
not sure in this summer whether Dortmund can dominate the bundesliga or even just finish as runner up again. but even being runner up is a bit tough.
Bellingham has already been signed by Real Madrid. He is joining the team by July 1. They paid more than 100 million euros to sign him so Dortmund have still made a huge profit in this transfer. However losing one of their important players has made them weaker temporarily. But I expect Dortmund to fill his place with another talented player as soon as possible.
In the same way we will see if there will be others leaving the team as well. Dortmund are full of skilled young players and they always keep the squad that way to apply their vision. We will always continue to see this kind of players coming and leaving. It might be sad to lose some of them right away maybe but at least the profit is really big.
