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.

He knows the dressing room, the pitch and the club. But, above all, he knows the feeling of playing for the Werkself at the BayArena: Moussa Diaby is back in Leverkusen after three years. The lightning-fast winger has signed a contract with Bayer 04 until 2031 and he will once again wear the number 19 jersey. The left-footed player previously played for the club from 2019 to 2023, having arrived in the Rhineland from his native France as a promising young talent and eventually leaving the club – having established himself as one of the Bundesliga’s best attackers – to join Aston Villa in the Premier League. Now he has returned to Bayer 04 from Al-Ittihad FC in Saudi Arabia.
