Union Berlin’s fairytale run at the top of the Bundesliga continued on Sunday, when a gaffe by Borussia Dortmund goalkeeper Gregor Kobel helped them to a 2-0 victory over Edin Terzic’s side.
Janik Haberer’s two first-half goals put Union in dreamland as they extended their five-week run at the top of the table and handed Dortmund their fourth defeat of the season.
The visitors’ horror began when Kobel handed Union the opening goal on a silver platter.
As he stepped up to receive a routine backpass from Raphael Guerreiro, Kobel slipped on the grass in his own penalty area, allowing Haberer to tap the ball into the empty net.
Soon after, Haberer doubled the lead, blasting the ball into the bottom corner after Union had danced through the sluggish Dortmund defence.
Terzic introduced three forward players at halftime to try to make a comeback, but Union continued to enjoy the better chances.
Early in the second half, Timo Baumgartl forced a sharp save from Kobel, and only a desperate challenge from former Union defender Nico Schlotterbeck denied Andras Schaefer a few minutes later.
Dortmund pushed strongly in the closing 15 minutes, forcing Union goalkeeper Frederik Ronnow into three superb saves.
Former Dortmund striker Steffen Tigges scored twice to lead Cologne to a 3-2 triumph over Augsburg in the early game on Sunday.
Florian Niederlechner squeaked the ball past goalkeeper Marvin Schwaebe after a long ball into the box to give Augsburg the lead.
Tigges equalised shortly after halftime with a superb first-time strike, and was then involved in the build-up to Cologne’s second, as Denis Huseinbasic put the hosts ahead.
When Augsburg did get forward, they were brutally efficient, and Daniel Caligiuri swept in an equaliser just a few minutes later.
Tigges, on the other hand, remained a thorn in the visitors’ side until the end, poking home the winner with just nine minutes remaining.
