Leipzig are slightly more favored when facing Eintracht Frankfurt, I think it's reasonable because Leipzig is acting as the host. Indeed, Eintracht Frankfurt is statistically slightly more consistent at this time, but Leipzig is more favored based on head to head. In my opinion, it seems that both teams will be able to score, and that is a better choice if want to bet. Meanwhile, Leverkusen is getting the right momentum to move up to the runner-up position, but on the condition that they must be able to beat Augsburg and hope that Eintracht Frankfurt draws or loses to Leipzig.
Leipzig actually having the hosting advantage but have you considered the performance of Frankfurt recently? Literally this season I hope I will not be wrong to say they have got even better pattern around their game than Leipzig does, I wouldn't want to exaggerate but Frankfurt has been considerably very productive that they may look like a threat to Leipzig even not minding the fact that they are going to be hosted by Leipzig, they have a very stable midfield and their attack isn't doing bad so if Leipzig has got a defense deficit, they may have to fix it or loose even at home. I believe even the casino isn't certain about what the outcome is going to look like that's why the odds aren't far apart by a significant difference.
