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.
