Dusseldorf won for the third time in 13 Bundesliga matches on Friday as goals from Robbie Kruse and Stefan Reisinger helped the side to a 2-0 win over Hamburg.
The result lifts Dusseldorf two points clear of the relegation places and to within one point of Hamburg.
Dusseldorf struck just before halftime on the break as Andreas Lambertz set up a good chance for Kruse that he calmly slotted into the lower left corner of the net beyond the reach of goalkeeper Rene Adler.
Kruse then turned provider in the second half to help double the advantage for Dusseldorf when he picked out Reisinger inside the area, allowing the forward to beat Adler with a shot inside the left post.
From there, Hamburg had more of the chances but the home side was able to protect its clean sheet to snap a seven-game winless streak.
Bayern Munich enters the weekend eight points clear at the top of the table and the club hosts sixth-place Hannover, which has lost three of its last five games.
Schalke and Eintracht are level on 23 points in second place and they will get together at the Veltins Arena with Eintracht having won just once in four matches.
Borussia Dortmund has taken 10 points from its previous four games and tries to keep that momentum going at Mainz, Nurnberg visits Greuther Furth in a match pitting two of the bottom three teams in the Bundesliga, while Wolfsburg tries to move a bit further from the bottom three with a home win against Werder Bremen.
