Hamburg secured a crucial 1-0 victory over Bayern Munich to claim the Bundesliga top spot temporarily. Croatian striker Mladen Petric scored the only goal of the game before half-time, to give his side all three points in the opening match of league's second half. HSV reached 36 points, leading Bayern and Hoffenheim by one point, but the latter host Energie Cottbus this weekend. Five other games will be played on Saturday as well, including Mohamed Zidan's Borussia Dortmund against Bayer Leverkusen.
