The DFB Pokal, Germany’s major cup competition, comes into focus this weekend, off the back of two well-earned wins in the 2.Bundesliga for Union Berlin.

Now, Jens Keller’s side are focused on 1.FC Saarbrucken, the fourth-division club, who will be hoping for an upset at the Hermann-Neuberger-Stadion in Völklingen. It’s been more than a decade since Union and Saarbrücken locked horns in competitive football. The side from Saarland lost both games to Union in 2001-02, the first season in the 2.Bundesliga for the Köpenick club.

Saarbrücken have been forced to move away from their traditional home and will walk out in Völklingen. “We have to take them seriously,” said Keller. The club’s traditional home is being rebuilt at the Ludwigspark Stadion, therefore the venue is at the Hermann-Neuberger Stadion.

But despite having two tiers worth of advantage, Keller urged cautiousness ahead of the task at hand. “They got off to a great start. They are a 3.Liga team in my opinion and I’m sure they will be top by the end.”

Around 1,000 Union fans are expected to make the trip to Völklingen, with increased security expected around the ground. Fans will be able to buy products from the club’s mobile shop (Union-Fahr-Zeughaus) in the away section of the stadium.
