Leipzig have really made a solid sum of money in player sales during this summer. They have lost quite much strength at the same time but I don't think they are very unhappy with the current situation now. Because they aren't much different than Dortmund on this topic. Their main vision is also to make as much profit as possible by being active in the transfer market.

In this way they are still making a lot of money even though they don't win the Bundesliga title. This is at least enough to keep their finances strong.

To be able to become more competitive for titles they need to build their squad according to it and focus on keeping their players for a long time instead.
