I think failing to convince a player to stay is the main reason and not selling them. What if player puts a pressure and declines contract extensions? Then obviously it will be loss for Dortmund later on as the player will move out for free. I feel that Dortmund should find a good way to convince a plyer to stay as like this they are only waiting for Bayern to become inconsistent in the league and get the title for themselves. Dortmund are just not putting any effort to win the title like this .
I dont agree on that , and Dortmund putting a lot of effort in it to win the title but they doing that on a different way.
For sure they would be have the Money for getting very good players and hold good players , but for how long would this be working ?
Even they lost a lot of very good Players in the last years i think they are on right way and making every season little steps forward to catch up with Munich in league.
If Borussia Dortmund had not sold their players in the last 2 seasons, they would probably be the biggest championship candidate this year. If Bayern Munich becomes champion every year, Borussia Dortmund, which sells its best players every year, also has an impact on this. However, they somehow manage to fill the shoes of those players. Dortmund is a different team.
I must say that Dortmund's strategy confuses me. In one way, they make and develop these great players, which makes us fans excited about what the future holds. Suddenly, boom! They dispose of them. It's like watching a really interesting TV show and then finding out that the main character goes after the first season. Still, the fact that they are still a strong player in the league shows how tough they are and how good they are at finding talent. Bundesliga wins may be due in part to Dortmund's habit of moving players, but I hope the story takes a turn soon
