Borussia Dortmund threw away their lead twice to pick up only a point as they drew 2-2 at home to Wolfsburg on Wednesday night, and remain in the thick of a relegation battle
Pierre-Emerick Aubameyang gave Jurgen Klopp's crisis club the lead early on, but Kevin De Bruyne levelled for the visitors before half-time.
A goal from Ciro Immobile looked like it was going to be enough to earn the Westphalians a third straight home win, but Naldo silenced the Westfalenstadion late on by snatching his side a point.
The result leaves Dortmund inside the bottom three ahead of the final round of matches in 2014 at the weekend while Wolfsburg remain second, 11 points behind league leaders Bayern Munich.
Borussia Monchengladbach boosted their goal difference to move above Bayer Leverkusen to third thanks to a 4-1 win over bottom-placed Werder Bremen.
Max Kruse, Oscar Wendt, Christoph Kramer and Branimir Hrgota all found the back of the net in a comprehensive win for Lucien Favre's side with Zlatko Junuzovic scoring Bremen's consolation.
To make matters worse for the visitors, they ended the game with 10 men after Luca Caldirola was given his marching orders.
Stefan Kiessling's 79th-minute effort was the difference as Bayer Leverkusen beat Hoffenheim 1-0 -- although they slipped to fourth after Gladbach's crushing win.
In what proved to be the clash of the night, Hertha Berlin blew a 3-0 and 4-2 lead as they were forced to settle for a 4-4 draw at plucky Eintracht Frankfurt.
Goals inside the first 37 minutes from John Brooks, Anis Ben Hatira and Julian Schieber appeared to put Hertha on course for all three points but Stefan Aigner pulled one back just before half-time.
Haris Seferovic narrowed the deficit to one goal and although Peter Niemeyer put Hertha ahead with 10 minutes remaining, Alexander Meier struck twice in added-on time to rescue a thrilling point for Eintracht.
Goals either side of half-time from Eric Maxim Choupo-Moting and Roman Neustadter helped Schalke hit back to win 2-1 at Paderborn, who had taken the lead through Kaan Ayhan's own goal.
