I feel that Dortmund fans should literally stop going to the stadium if
Halland is sold to Bayern, and I’m aware that it’s only a matter of time before he’ll leave, but irrespective of where Dortmund finishes this season he should not be allowed to join Bayern.
Haaland would only be a reinforcement for Bayern if at the same time Lewandowski would not leave the club and there are indications that he might not extend his contract. Otherwise, Haaland would simply be an equal replacement to Lewandowski. However, I believe that should Haaland move to Bayern, Lewandowski will leave the club because Bayern's current successful tactics and gameplay cannot be continued with both players at the pitch at the same time.
