I think what will keep the rivalry alive are the matches between Bayer Leverkusen and Bayern Munich. The scores in these matches will directly affect the championship. In addition, the performance of teams such as Frankfurt and Dortmund, which can prevent them, will also be decisive. I would like Bayer Leverkusen to win. The championship needs a change now.
I think that indeed the biggest hurdle for Leverkusen for the moment is to get back out of the Christmas break and win the first game against Augsburg. The interruption seldomly benefits teams like Leverkusen when they are running like clockwork. If they can get out of the break and instantly beat Augsburg, it would be so important for the rest of the season. Psychologically I am a bit afraid because Bayern starts into the second half of the season with a home game, which they are unlikely to tie or lose. This could create some negative momentum, but of course I hope for Leverkusen to continue with their impressive performances.
