Even they are still in their way of having youths in their team and after few years sell them for big amount because they can't stop this all which is helping strongly for their financial strength but now fighting for title is also very impressive.
I really hope that Dortmund is considering changes in the team so that they will have some chances to compete against Bayern Munich for the league title. In other words, they are making changes to make successful business happen for these players in the future. To be honest they are not even close to Bayern Munich in terms of giving them a proper fight. However, I would like to see them at least give it a try and not always think about money. The team will eventually earn money if it does not simply focus on acquiring young players and selling them for a profit later and instead focuses on winning trophies.
