I guess you are wrong because you won't know having money is more important than a better place on the table for the managers.
Obviously, Dortmund prefers to earn more money from transferring players to other teams than using the players to have a better situation. Otherwise, the Dortmund we saw could easily win the Bundesliga title if they didn't sell Haaland before.
So, did you say that if dortmund can only rely to the haaland? Haaland was never winning bundesliga with dortmund unlike lewandowski which has been ever winning bundesliga 10 years ago.
No guarantee even if haaland is still playing in dortmund and the club can win bundesliga trophy from bayern. The fact that if bayerns are still keeping its record in the bundesliga to win this league for more than 10 years in a row.
That proves that if there's no club that can prevent bayern to win the league. Dortmund was losing in the previous season due to the weak mentality that owned by its players.
I will not think that halaand will have a good progress like he was in city when decided to stay even longer in the dortmund.
Football is a game for eleven players. Haaland has been playing in dortmund for several years but no achievement being achieved by him.
