In any case, it seems that Schalke is moving in that direction. Schalke have managed to get back into the Bundesliga 1. But only for one season, because they have not worked sustainably. Many clubs see a relegation as a slip-up that only happens once. And that is probably also the problem. You have to admit to yourself and understand why the relegation have happened and then fix the mistakes. But the people in charge who made the mistakes do not want to admit that to themselves.
Schalke lost 2-1 at home to Hertha Berlin, putting its position in trouble for this year's Bundesliga. They have only 7 points in 9 matches and if it continues like this, they will be relegated from Bundesliga 2 to the lower league. Hamburg, on the other hand, is playing very well to get the upper league opportunity it missed last year. I think one of the teams that will emerge this year will be Hamburg.
