1. FC Union Berlin will aim to get back to winning form when Borussia Dortmund make the trip to the Stadion An der Alten Försterei on Sunday afternoon at 15:30 CET.

Review — The last match:

1. FC Union Berlin suffered the first defeat of the new year, going down 0-2 at FC Augsburg in the Bundesliga last Saturday. Markus Weinzierl's team prolonged Union's winless trips to the VVK-Arena in Augsburg since the Köpenick club were promoted to the Bundesliga. Union were captains of their own downfall, going behind after 16 minutes when a mistake was punished by Michael Gregoritsch. It was largely one-way traffic for Augsburg with Christopher Trimmel forced to clear off the line on 26 minutes. Helped by the return of top scorer Taiwo Awoniyi after the African Cup of Nations, Union came back into the game but the Nigerian couldn't take his opportunities. Niko Gießelmann headed over as Union put on more pressure but Rafal Gikiewicz kept his former club at bay. Andre Hahn scored a long-range piledriver after the interval to put the game beyond doubt. Urs Fischer handed a debut to Sven Michel for the last half an hour following his arrival from Paderborn.

Dortmund — Opposition Report:

Borussia Dortmund are Bayern Munich's major competitor for the league championship, occupying second place in the table. However, Marco Rose's side are nine points behind the German champions and can't afford further slip ups. Dortmund rely heavily on Erling Haaland to put the ball in the net on a consistent level. In 14 games in the Bundesliga, the Norwegian has fired 16 times and created another six goals. Dortmund have the second-best attack in the Bundesliga with 54 goals in 21 games. Defensively, Rose has had to deal with some issues as Dortmund trail only Greuther Fürth, VfB Stuttgart, Hertha and Borussia Mönchengladbach in goals conceded.

Dortmund — The coach's view:

1. FC Union Berlin head coach Urs Fischer said: "Borussia Dortmund are of course exceptional in playing with the ball and always finds solutions in tight spaces. In addition, they always come up with the pace in behind. This team consists of  difference makers who can all decide a game. We simply need a perfect game."

Personnel:

Rani Khedira is suspended. Keita Endo has an illness but has tested negative with PCR. Urs Fischer confirmed the Japanese winger would train on Saturday, if healthy. Four players are unavailable due to positive test results: Jakob Busk, Niko Gießelmann, Andreas Voglsammer and Dominique Heintz.
