Borussia Dortmund actually has great potential to be able to compete even more tightly with Bayern Munich. But yeah, I see they are not serious about it, they just want to have an advantage in terms of money for this team. The result as we see, they can not compete with the rulers of the Bundesliga, Bayern Munich. This makes the Bundesliga monotonous in terms of competition.
Borussia Dortmund has a great potential alright but they are riding the number 2 spot in the Bundesliga all thanks to Erling Haaland, but I think Dortmund can push even further if Erling Haaland didn't get injured and have many absences for most of the games, well, it is not his fault and he has said in an interview that he really hates himself for getting injured and not able to play full time for the season, but for the next season Dortmund would have to play in the Bundesliga without a reliable striker because Erling Haaland is transferred to Manchester City
This is true, Robert Lewandowski is reportedly looking for greener pastures or perhaps higher pay and his most likely destination is either of Real Madrid or Barcelona. With Haaland already signed by Pep at Manchester city, it is either Bayern get a younger striker, or perhaps rely on academy graduates to fill the shoes of their goalscoring talisman. With Sadio Mane signing imminent. I think Bayern will conduct their businesses well
I really think you didn't have any idea about the news on Robert Lewandowski, right now Lewandowski is not on good terms with Bayern Munich, the club wants to keep him next season, but as you said he already wants to be out of Bayern, and wants to be with Barcelona, and if Bayern would still not let him out of the Bundesliga he will be the one to buy out his contract with a 2004 webster ruling that players 28 years and above can pay compensation to terminate his contract with Bayern, and by doing this he doesn't really care about higher pay because Barcelona has backed down in getting him because of his higher price, that Bayern have set, and Barcelona really can not afford to his fee, but Lewandowski still looks forward to the transfer.
