Should the Werkself avoid defeat in Köpenick, they will equal the Bundesliga record for longest unbeaten start to a season. That is currently held by Bayern Munich under Pep Guardiola in 2013/14 at 28 games, before a 1-0 loss in Augsburg on Matchday 29. That Guardiola side are also the only team ever to have more points after 27 matchdays than Leverkusen this year, with 77 instead of 73.
Bayer 04 have lost only one of their 12 competitive encounters with Union (W7, D4), which came in Berlin in January 2021 (1-0). However, the Werkself are without a win at the Alte Försterei since February 2020, earning only two of a possible nine points from the last three Bundesliga visits.
Life had only been positive for Union following their maiden Bundesliga promotion in 2019, achieving finishes of 11th, seventh, fifth and then fourth last season to qualify for the UEFA Champions League for the first time ever. This term has been much tougher, though, and prompted the departure of long-time coach Urs Fischer in November 2023. Under successor Nenad Bjelica, the Irons reached the mid-point of the season in 15th place. Bjelica and his team have turned things around this year, earning 15 points from their 10 games in the second half of the campaign. Find out more about today’s opponents in our opposition profile.
