UEFA have appointed experienced Englishman Michael Oliver to oversee the game. The 37-year-old has been a FIFA referee since 2012 and has previously taken charge of two Bayer 04 matches. The first was a 1-0 win at Rosenborg in the 2012/13 Europa League, followed by a 2-0 victory at Lokomotiv Moscow in the 2019/20 Champions League campaign. Oliver will be assisted by compatriots Stuart Burt and Simon Bennett. Chris Kavanagh is the VAR.
Atletico were also one of Leverkusen’s opponents the last time they competed in the Champions League back in 2019/20. In fact, this is the fourth season where Bayer 04 and the Madrid club have come up against each other. Previous encounters were in the 2014/15 round of 16 (Atletico won on penalties), the same stage of 2016/17 (4-2 on aggregate for the Spaniards) and in the aforementioned group stage in 2019/20, when the Werkself won 2-1 at home and lost 1-0 in Madrid.
Both teams probably expected their campaigns to have started differently. While the Werkself are currently second bottom in the Bundesliga, while Atletico themselves won only two of their first four league outings. A win at the weekend after their opening 2-1 victory over Porto in the Champions League perhaps shows signs of improvement. Here’s more on our opponents.

Lying third in the Bundesliga, the Werkself made a faltering start in 2026 after the winter break, but gradually rediscovered winning ways and, as in the previous campaign, were among the top 16 in Europe and the top four in the DFB Pokal. In the Bundesliga, the Werkself also remained in the race for Champions League qualification right to the end. However, because setbacks repeatedly crept into the Werkself's performances between good displays and crucial games, it was not quite enough to secure a UCL spot in the end. A season with many ups and downs brought sixth place and qualification for the UEFA Europa League. Part II of the review of the 2025/26 season.

Following the final match of the 2025/26 season, the prevailing feeling was naturally one of disappointment after missing out on qualification for the Champions League. The Werkself finished the Bundesliga in sixth place, meaning they'll start the 2026/27 campaign in the Europa League. "But to talk negatively about everything now because of that would be wrong," stressed captain Robert Andrich following the final game, knowing that the past year at Bayer 04 was marked, more than almost any other, by the start of a new era and the courage to change – and in particular, the belief in a positive direction. Everyone was aware this process would need time. The first part of the 2025/26 season review.
