The best defence of this calendar year play host to the second best: Union Berlin have only conceded 11 goals in 2023 and the Werkself just 15.
This clash brings together Jeremie Frimpong and Union’s Sheraldo Becker, the two players who have made the most sprints in the league this season. For the Leverkusen player it is 950 and the Irons striker has made 922.
2,500 Leverkusen fans are expected to make their way to the capital to support the Werkself in the game against the Irons at the An der Alten Försterei Stadium. Over the course of the 2022/23 season, Bayer 04 have been able to count on the backing of an average of 2,000 fans at their away games. The club is grateful for this fantastic support.
The German Football Association (DFB) has appointed Marco Fritz as the referee for the game at the An der Alten Försterei Stadium. The 45-year-old has been in charge of 21 games involving the Werkself to date (11 wins, three draws, seven defeats). His assistants today are Dominik Schaal and Marcel Pelgrim with Marcus Schmidt in action as the VAR official.
Last weekend, Union Berlin secured a deserved 1-0 win at Borussia Mönchengladbach and thereby extended their lead over fifth place to four points. The Irons are third in the table on 55 points. That is just two points less than the previous best return for the club in the Bundesliga from last season. They are on course to qualify for the Champions League for the first time in their history.
