Dortmund started the season much better than Bayern Munich. They demolished Frankfurt 5-2 and improved their morale at a very high rate. Haaland was the player of the match that's for sure. He had 2 goals and 3 assists which was a really insane performance from the young lad.
Dortmund are keeping Haaland for this season too but I don't think that they will be able prevent him from leaving next summer.
