Leverkusen and Bayern Munich have the potential to lose points in this match if they make a small mistake because of course the host will also fight to get points in order to improve the standings. So it is very true as you said, for now there is no team that dominates the Bundesliga because both Leverkusen and Bayern Munich have the same opportunity.
I disagree with the idea that both Bayern Munich and Leverkusen both have the same chances of losing points in their next match. I don't think Borussia Monchenglabach will be able to cause an upset against Bayern Munich. Leverkusen can still drop point when they visit Dortmund in their next fixture of the Bundesliga because Dortmund will also be looking to improve their performance on the standings.
they can still lose points, but with a different percentage, that's what makes them different in the matches they will face this week. Actually, in every match, all teams have the opportunity to lose points, no matter how strong they are, but the opportunity to lose points will always be there, but maybe what makes the difference is where the percentage is different.
Like what you said, when Bayern Munich faces a team that can be said to be weaker than them, their chance of losing points will not be the same as Leverkusen who will face a team that can be said to be one of the big teams in the Bundesliga.
