Robert Lewandowski's second-half goal was not enough to prevent Bayern Munich from slipping to a shock defeat at home against Hoffenheim.
Bayern Munich suffered their first defeat in 21 Bundesliga matches as Hoffenheim ran out 2-1 winners at the Allianz Arena courtesy of Sargis Adamyan's brace.
The Armenian striker scored either side of Robert Lewandowski's 11th league goal of the season to earn Alfred Schreuder's struggling side a shock victory over the champions, whose flat performance merited nothing more than a defeat.
