If I compare between Bayern Munich and Dortmund, I think I'm more interested in Dortmund. Because after all, Bayern Munich only has a record as a club that really dominates the Bundesliga by winning consecutive titles. But in fact, Bayern Munich also quite often get great players from Dortmund. Also about Dortmund, even though Dortmund often sell key players and star players, but Dortmund has always managed to build a team well. The proof is, Dortmund has always managed to challenge Bayern Munich in the title race and because of that, I think Dortmund is a very unique team. Because no team can produce great players every season like Dortmund and also be willing to sell them, it's like a tradition that only Dortmund seems to have.
You can't compare Dortmund to Bayern Munich because Munich are the best club in the Bundesliga, they are in the top every season in the league and even perform well in the Champions League but last season their performance was very weak, and they too are in the best club in the world, last seasons Dortmund try there best to win the league but they can't, and now they need some players because they sold their best midfielder in Dortmund to Bayern Munich. I'm not the one who made that post, it is @hahay. It seems like you have quoted the wrong person.
I wonder what Bayern Munich's plans are about signing a centre-forward these days. They made their first offer for Kane but it was way lower than the amount Levy wanted for him. Considering that the first offer was around 75 million euros or so it doesn't seem like Bayern Munich are keen on spending 100 million or above for Kane.
Honestly I started to think that they won't pay that much for him and instead they will go for cheaper alternatives.
