Bellingham was Borussia Dortmund's biggest weapon. The same situation was true for Haaland last year. The team got a little worse after Haaland left. After Bellingham left, Dortmund got worse. Dortmund is a team that is adept at recruiting young and talented players. They may be bad this year, but they can make up for that deficiency soon. The observer team is very good.
It could be said that this season Dortmund will be even worse. It will be difficult for Dortmund to get anything this season after they lost players like Jude Bellingham and Raphael Guerreiro in the same season. This will also have an impact on the UCL league of course, especially since they are in a strong group, of course they will find it difficult to get through the group phase with the current players. I think the Bundesliga this season will be a competition between Bayern Munich and Leveskusen, I don't think Dortmund will be able to compete with the current squad.
However, Dortmund could not replace Holland with a striker as good as him. The Dortmund team unfortunately missed out on the title last season. But I hope to do something good this season.
