Hertha Berlin earned a critical point in their fight against relegation with a scoreless draw at Borussia Monchengladbach, who could see Schalke pull away in the race for the automatic UEFA Champions League berth.
Gladbach have collected just one win in their last seven games and moved to 52 points, while Schalke play tomorrow and hold a two-point gap. Hertha have a win and draw in their last three games for 27 points.
Gladbach were hit with an injury concern in the opening minutes as forward Marco Reus received a knock on his right knee by Christian Lell. Reus was then replaced in the 20th minute by Igor de Camargo.
Relegation-threatened Hertha were clearly set on not conceding a goal and, without their main creative force, Gladbach struggled to build up chances. Juan Arango decided to try his luck in the 29th minute from long range but it went just over the bar.
De Camargo had the hosts' best scoring opportunity eight minutes later as Mike Hanke fought his way through the left side and fed the Belgian the ball near the edge of the box. But De Camargo's shot went just inches wide of the left post.
Hertha finally threatened in the 56th minute but Lell's shot from 12 yards after a pass from Raffael was blocked by Martin Stranzl. Stranzl nearly scored for Gladbach in the 67th minute but his header from five yards from a free-kick was stopped superbly by Hertha goalkeeper Thomas Kraft.
The hosts struggled to find their way through the compact Hertha defence and Arango once again tried a long blast in the 75th minute. The visitors began to push forward more in the closing stages and Raffael's long blast forced Gladbach goalkeeper Marc-Andre ter Stegen into a good save in the 85th minute.
