Wagner double earns Hoffenheim first win in five matches
Germany forward Sandro Wagner scored twice as Hoffenheim beat bottom club Cologne 3-0 on Sunday for their first victory in five Bundesliga matches to move back up to fifth place.
Wagner, battling for a spot in Germany's World Cup squad next year, doubled their lead with a 56th-minute penalty and volleyed in an Andrej Kramaric cross at the far post 10 minutes from time.
Cologne failed to show any of the form that helped them crush BATE Borisov 5-2 in the Europa League and remain in last place on two points and no wins from 11 games.
Champions Bayern Munich opened up a four-point gap at the top after their 3-1 victory over title rivals Borussia Dortmund on Saturday. Bayern are on 23 points with RB Leipzig, 2-1 winners over Hanover 96, in second on 22.
The Wolves missed a penalty and had two efforts disallowed after advice from the video assistant referee in the first half but still led 3-2 before Selke got a lucky bounce to tap in the leveller in the 84th minute of a topsy-turvy encounter.
Wolfsburg are 14th on 11 points with Hertha in 11th, three points ahead.
Third-placed Dortmund are on 20, level with Schalke 04, and Hoffenheim are fifth a further point behind.
