I won't make risky bets like you, even Bayern, this season. I won't put my faith in either. Only Leverkusen is probably my safe bet. I bet Leverkusen will overthrow Bayern's throne this season if Bayern continues that erratic performance.
I am also the same as you. I am a bettor who prefers safe bets. This season I only feel safe if it is Bayern Leverkusen. And regarding the title, I am sure Leverkusen will win the title this season. Even though the competition with Munich is still tight with only a 4 point difference, I see that Munich showed several weaknesses when they lost against Frankfurt. Leverkusen has never lost at this time. But Munich is also still quite competitive because there are still many games left in the season.
Bayern too, at least for me. I do feel safe when I am betting on leverkusen and bayern, all the other teams are a little bit more confusing to me. As we all know neither Byaern nor Leverkusen won all their games so far, they had games where they had a draw, or even a loss. So, it is not easy to bet on these teams and I get that, but it doesn't mean that we are going to end up with something like that quickly, it just means that we are not going to end up with anything that will change much.
I hope that we could get to a point where it is going to be easier to handle, it should not be all that confusing and we could make it work as well. Bundesliga has always been a difficult league to bet on, and unexpected results are expected here. I believe that if these two top teams continue down the same path that they are going right now, it is going to be a very very profitable season for us, they are doing wonders for all the people who bet on their game.
