Great game in Stuttgart. & goals including two own goals doesn't happen very often. Leverkusen did what they were famous for last season: turning things around in the last minutes.
Potentially important win that makes things a little bit more interesting. Leverkusen is now 6 points behind Bayern, which is still a lot, but Bayern unexpectedly lost points in their last 2 league games against weak clubs, which could be an indication of some small crisis in the team (although their great Champions League performance doesn't fit this theory).
Anyhow, nothing is yet decided and Leverkusen still have a chance to do what they have never done in history and win the league twice in a row.
