1.79 for Leverkusen to win is great I think. Leverkusen won in their last three head-to-heads. I don't see any reason not to see another win by them here. 
Xabi Alonso has started this season well too. First a German Super Cup won despite being one man down. Later a start with a win in the Bundesliga... I expect this winning streak to continue on this week as well. Both teams to score and over 2.5 goals could also be nice options (even over 3.5 goals would be logical).

They can't keep winning forever and it's expected that the Leipzig will steal some points eventually.
And it shouldn't be overlooked that Lepzig is a very solid and consistent team. They've been finishing in the top 4 (Champions League places) for the last six years in a row. This should be accounted for.
If Bayer is to lose points this season, it would be to teams like this one. Personally I wouldn't be betting on this game.
Home advantage should work in favour of Bayer though, as Leipzig tended to perform better at home than in away games.
