That's really unfair on Dortmund. I'd argue they have more ambitions than us, especially in the transfer market. There's a reason why they have won the league more recently than us and has done better in europe, have a far better squad this decade.
They obviously ain't as big a club as us, which is why they have needed to sell and use the money to build squad after squad. We have a far bigger fan base and tv revenue and we can't even have a better squad. And we really don't sell well too.
It's not easy to take good youngsters. Bellingham, Sancho, Haaland etc would have even started for us too. We can promise as much gametime and more money.
