Union Berlin are on a high after the 5-0 hammering of 1.FC Kaiserslautern at the Stadion An der Alten Försterei on Monday.

The win on Monday ended a run of five games in the 2.Bundesliga without a victory.

“With the way we went into the Kaiserslautern game, we made them feel insecure. They went in highly motivated after the coaching change, but we showed from the first minute that there was nothing to be gained from us, Victories do each team good, they give them self-confidence. After five games without a win, the three points and performance was particularly good. We haven’t scored enough points so far, so the success on Monday was great for mentality,” said the Union coach.

The focused turned to the opening game rather than Monday. “We’ll have to be prepared for this,” started Keller. “It doesn't matter whether they have two home games in a row. We will do a few things different tactically, because Aue shapes up differently to Kaiserslautern. No game is 1:1 transferable. We want to focus on our qualities and I have always said that it will be difficult to score against us. The prerequisite, however, is that we deliver 100 percent.”

This summer has been a transition period for Erzgebirge Aue following the departure of coach Domenico Tedesco to Bundesliga side Schalke. Both Thomas Letsch and Robin Lenk had spells in the dugout, before Hannes Drews was confirmed permanent successor to Tedesco. Since the 35-year-old’s appointment, Aue have won three of four matches and sits in a respectable seventh place.

“Aue have played a couple of good games despite some defeats. They are extremely compact and very well organised. They have players up front who know exactly where the goal is. It’s going to be a tough game, and we have to be prepared for it. We’ve won there many times before, and we’re confident of doing that on Saturday,” said Keller, who has a clean bill of health in his squad with Kenny Redondo and Christoph Schösswendtner back in training this week.

With the stadium undergoing extensive reconstruction, there are no more tickets available for travelling Union supporters. Gates at the Sparkassen-Erzgebirgsstadion are open from 11am, with kick-off at 1pm on Saturday September 30.
