36 games; 103 goals and 0 losses in total.... This is just an insane form by Leverkusen.

The impact Xabi Alonso has made on this team is just huge. It is really hard to describe.
Bayern Munich got a whopping 8-1 win against Mainz last week maybe but this hasn't changed anything about the gap with Leverkusen in the standings anyway. The only thing Bayern Munich can do to complete the season and move on in their life with their second position. Even that position is under the threat of Stuttgart a little as the gap is only four points. But I assume Bayern Munich wouldn't lose their current placement at least.
