Bundesliga Preview: Bayern host Hamburg

Schalke and Augsburg are level on points in third and fourth and are both on the road this weekend.

Victory against Klopp's former club Mainz at Signal Iduna Park on Friday would haul the 2011 and 2012 champions level with their opponents on 22 points.
Stuttgart are propping up the table, a situation they will hope to remedy when they face seventh-place Hoffenheim on Saturday - themselves aiming to end a slump of three straight losses.
