I agree, not only the position where they finished the league but also the game they showed on the field is not promising for the future. I don't think Leipzig will even be in the top 4 unless big changes are made in the team next season.
I was literally expecting them to have an easy winning in the match. But, it turned out Leipzig struggled to equalize the score. They almost lost the game, if not for Orban who scored a die minutes goal. Although, Bielefeld defense were very tight. Leipzig have to improve their squad with some talented players, otherwise, I don't think next season will be productive to them. However, Bielefeld couldn't make it out of the relegation zone, and were unfortunately relegated to Bundesliga 2.
