<text>  Borussia Dortmunds mini renaissance which had seen them win four Bundesliga games in succession came to a halt, as they were held to a frustrating goalless draw at Hamburg. The tight contest saw the visitors dominate possession, with Pierre-Emerick Aubameyang and Marco Reus typically at the heart of Dortmunds attacks, but try as they might, they could not circumvent a well-drilled Hamburg defence. Despite an early injury to captain Johan Djourou, the hosts were able to weather the storm from Jurgen Klopps men.

For Dortmund, it is a blow to their aspirations of qualifying for continental football next season, while relegation-threatened Hamburg remain without a win in their last four league outings. Dortmund had started the game strongly with Reus, passed fit after an injury scare earlier in the week, finding Aubameyang with a free-kick only for Hamburgs Djourou to make a timely intervention. Hamburg striker Nicolai Muller fired wide a few minutes later, but chances otherwise came at a premium during the first-half. Djourou, following a head collision with a Dortmund player, was substituted in the 18th minute. Hamburg head coach Josef Zinnbauer is incensed after a refereeing decision goes against his side .

It was a routine that seemed to repeat, with every Dortmund effort finding itself wide, blocked through the final pass.
