Many reasons for that.
- Lucio and van Buyten doing an awful central defense job, especially Lucio, they leave it all up to Kahn, who is world-class this season, but cannot stop Bayern losing on his own.
- The gap which Ballack's leave opened, has not been closed successfully. He's still missing a lot. Van Bommel, although playing good recently, is not a replacement for Ballack.
- World-Cup heroes like Schweinsteiger and Lahm struggled a lot trying to find their form from the summer and they're still not at 100%.
- Bayern's striker hope, Lukas Podolski did not get into them at the beginning of the season. He did not feel Felix Magath has faith in him. Claudio Pizarro only shined in CL. In the Bundesliga, he could hardly been seen on the pitch. So Makaay was mostly on his own and not in the form of his life in the first half of the season.
