They're all in for the gains and profits they get else they wouldn't have messed up the chance they got to win the Bundesliga League Competition which they haven't won in years it's sad to see though.
Jude Bellingham is a big name but they lost Sancho, Erling Haaland and some other defender's and still kept the fire burning. Jude Bellingham leaving is no excuse, how many goals did he score for Borrussia Dortmund by the way. That's another expensive excuse to give out now. This season they have also been far from good. They seem to be following the same way they did last season. Let's just hope they get better in due time.
Dortmund would had been very tough to play against if they still had Halaand, Sancho and most especially Jude Bellingham currently in the team, they would had cause havoc for Bayern and probably stop their dominance in the Bundesliga but instead of keeping their players so as to be strong enough to win title they rather choose to enjoy the financial benefits that comes from selling them for a huge offer.
Well they're still a tough side and one of the top league contenders but I don't think they're very strong enough to challenge Bayern Munich or even Leipzig this season, and apart from the Bundesliga which they're doing alright their performance in the Premier league is very poor and don't even think they'll be able to qualify for the next round.
