Dortmund have been doing a lot in the previous season that people are always praising them and Bayern and not the glory they lost is coming back gradually, and they were always breeding good players look at were Haaland is coming from so what do you expect to come from other players. And they keep getting the best signings and that is what they are good at, they are always benefiting from the sell of those players because they sell them with good price.
They are both making money and breeding players to make more money the only difference I see with them is when they, are dropping in performance, but for players they are still trying because they were able to make it to the finals in the ucl last season at list that is a good sign this something that most clubs could not archive and Dortmund was able to, it is quite an archivement because when last did they even make it this far in the ucl so this shows that their is an improvement.
Dortmund with the quality it has managed to maximize big wins in the two Champions League matches it has played so far, with the big wins that Dortmund has in the two matches making Dortmund at the top of the Champions League standings. Because after all, other teams also managed to make two wins but in fact, only the total number of goals that made Dortmund at the top of the Champion League standings. But, in the next match Dortmund will play against Real Madrid and maybe this will be a challenge too because after all, in the previous two matches Dortmund played against Club Brugge and Celtic but against Real Madrid later, it doesn't seem easy for Dortmund to win with a big score like in the previous two matches.
But indeed, Dortmund have better results in the Champions League from last season too because after all, last season too Dortmund played in the Champions League final against Real Madrid. But in the Bundesliga, that Dortmund always failed to get the Bundesliga trophy despite having the chance to get it. Although Dortmund look very good in the Champions League, but I personally feel Dortmund will still be difficult to get trophies in any competition.
