Dortmund suffered a surprising first leg loss as the Austrian outfit secured a 2-1 away victory on Thursday evening to increase their chances of booking a place in the quarter-finals, reports Xinhua news agency.
Dortmund assumed control from the kick-off yet Peter Stoeger's men lacked any ideas on how to overcome Salzburg's well organised defence.
A set piece situation handed Dortmund their first chance but Andre Schuerrle's volley missed the target six minutes into the game.
The Austrians remained on the front foot and created another chance, as Marcel Schmelzer had to scratch away Munas Dabbur's effort off the goal line before the break.
Things went from bad to worse for the hosts as Berisha wrapped up his brace after Stefan Lainer's build-up seven minutes later.
