But it is obvious that Dortmund won't be able to keep him after the end of this season. Dortmund need him definitely. But it won't be easy for them to keep a great striker like him here for a longer time. I wouldn't be surprised if Haaland wants to start playing bigger than this already. He shouldn't waste his time at Dortmund also. They don't even achieve a proper title while having him too. Then, what is the meaning in staying here for Haaland? He deserves to experience a Champions League title for example.
Haaland is a goal machine in Dormund, and If he leaves Dormund, it will really affect the club. You can remember how Dormund lost most of the matches they played without Haaland. However, I think it will be a nice idea about Haaland moving to another club. He have to experience new challenges, and probably play in another League. Chelsea wanted to sign him last transfer window, but Dormund refuse to let go of him. Nevertheless, IMO, Premier League will be a good choice for Haaland.
