I think the first team to be relegated from the Bundesliga is Holstein Kiel. They are a very weak team, especially their defensive line is very weak, they concede a lot of goals in their goal. They lost 2-4 in front of Frankfurt in the match that just ended.
They got 1 point ahead of Bochum last week, but Bochum is also a weak team. If they continue like this, they won't even get 15 points until the end of the year.
I have to agree with you, Holstein Kiel is really very weak and if some things doesn't change very quickly, they will soon no longer be able to stay in the Bundesliga. Bochum is also very weak and only have one point from 5 games, but they are the more experienced team and will find it easier to pick themselves up. Only 5 games have been played but so far it is clear that Holstein Kiel were not ready for promotion last year.
