Hamburg (pictured), leaders going into the weekend's matches, failed to regain top spot on Sunday when they lost 3-1 at home to Wolfsburg and are a point behind Hertha.

Hoffenheim are third with 41 after a lacklustre 0-0 draw against Borussia Dortmund.

Wolfsburg, who displaced Bayern from fourth place, notched their fourth successive win after striker Grafite opened the scoring with a penalty, awarded for a foul on Edin Dzeko, in the 12th minute.

Grafite scored again in the 25th when Marcel Schaefer raced past Hamburg's Guy Demel and cut into the middle for the Brazilian striker to net his 14th league goal.
