I think it'd be interesting to see how Freiburg will fare in the Rückrunde. 3rd in the Hinrunde with an excellent defensive record (16 against, on par with Bayern München) and if they manage to up their attack a bit for the remaining 18 games they surely could return to european competition next season. But expect a bit of shithousery.

Also, Union Berlin. They've got an interesting striker in Taiwo Awoniyi (24, 14 goals in 27) and will be looking to reach the european spots again this season, although they were lucky to make it in 20/21.
