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.
Bayer 04 fans can also have all the most important information to hand in Champions League home games with Werkself LIVE. The flyer, which offers facts and starts on the clash with Diego Simeone’s team, is displayed in the BayArena. It’s also available for free online HERE.

For those who can’t be at the BayArena tonight, they can listen to the Werkself Radio in German. The broadcast starts around half an hour before kick-off. You can also keep up to date with the German live text. Both are available on bayer04.de and in the Bayer 04 app.

The Werkself beat Olympiacos 2-0 in the 2025/26 UEFA Champions League play-off first leg to claim a crucial victory in the Greek capital. After a focused first-half display with a number of presentable chances, Patrik Schick crowned a textbook counter to hand the Werkself the lead on the hour (60’). The Czech rounded off his brace when he headed in from a corner just 144 seconds later. Bayer 04 maintained their lead with aplomb to achieve a good position for the return leg in Leverkusen.

Bayer 04 and Olympiacos had only met twice before the current UEFA Champions campaign. After the encounter on Matchday 7 of this season’s league phase, the Werkself travel to face the Greek side for the second time in just four weeks for the knockout play-off first leg. The Black and Reds were dominant for large spells in mid-January but lost 2-0 after missing a number of presentable chances. The Werkself aim to do better on Wednesday night to “seize the chance for revenge,” as managing director sport Simon Rolfes put it. Here’s all you need to know ahead of the game in our matchday news.
