Seeing this odds makes me think, why not Dortmund who got odds @8.5? Whereas in the depth of the current squad, Dortmund is far superior to having more qualified players. Or maybe the bookies only take speculation of the results of Leverkusen past while still with Alonso. I have a hunch that is likely to have a runner up target while Dortmund currently also has the same target. This will be an interesting competition for the runner up position.
The reason why must be the final results of Leverkusen and Dortmund in the recent years. You know for 2 years, Dortmund haven't been able to finish the Bundesliga ahead of them.
Leverkusen are seemed more likely to win the league now because of that. But of course there are other parameters in this now.
Like the manager change there and Dortmund's having a much better manager like Niko Kovac...
