#3 Inconsistent performances by teams
Despite having a rather poor start to the campaign and a managerial change in between, Bayern Munich are runaway leaders in the Bundesliga. While much can be attributed to the Bavarians' form under Jupp Heynckes this season, their cause has been helped largely by the inconsistent performances of the rival clubs.
Having initially led Bayern by five points, Dortmund went on to have a torrid run, accumulating only three points in their next eight games and had to part ways with Peter Bosz. They are currently third in the league.
Last season saw the surprise uproar of Hoffenheim under young manager Julian Nagelsmann. While Die Kraichgauer started off well this season, beating the likes of Bayern Munich, Leipzig and Schalke, they now see themselves reeling in the seventh spot. The same goes for RB Leipzig who are just a spot above at sixth.
Such has been the plight of the Bundesliga that in the last four seasons, there has been no instance of all the top four clubs at the end of one season managing to end in the top four at the end of the next season. In fact, only Bayern have successfully managed to finish in the top four consecutively for the last five years.
