Dr Burak Yildirim is ending his time at Leverkusen this summer. The 45-year-old doctor for orthopaedics, emergency surgery and sports medicine will completely focus on his practice in Pulheim in the future. "I'd like to thank all players, management and staff for the years of support and trust. I'm proud to have been part of this great club for so long."
Yildirim came to Bayer 04 in 1996. He started as a youth coach before moving into the section providing commentary for the visually impaired after three years. He became the team doctor in 2013 and has carried out that role for the last ten years.
His successor is Dr Stefan Porten. The 46-year-old is taking over looking after the Bayer 04 first team squad immediately together with Dr Philipp Ehrenstein. Dr Porten was the team doctor for the Germany U20 and U21 teams and for many years and up to 2018 he was the team doctor at Borussia Mönchengladbach. Dr Porten has an orthopaedic surgery in Cologne.
Dr Daniel Lay, previously the team doctor for the Germany Women's U20 team, will look after the medical needs of the Bayer 04 U19 and Women's teams.
Sven Elsinger is returning to the Leverkusen physios. The 55-year-old is taking charge of the first team physiotherapy section, a position he held for 13 years up to 2021. Elsinger recently worked in the youth section at Bayer 04. His deputy is Ill-Han Yun.
Jonas Rath is a new fitness coach at the Werkself. The 43-year-old was the fitness coach at Borussia Mönchengladbach for the last three years. Rath takes over from Schahriar Bigdeli who occupied that role since 2006 after being a long jumper with TSV Bayer 04 Leverkusen.
Standing on the pitch where the Werkself players perform - for many Bayer 04 club members, this wish became reality at this year's Members' kickabout. Around 400 active participants of all ages took the opportunity to experience the BayArena from a new and special perspective. And there was also plenty going on in the stands: The event attracted more than 1,000 visitors in total and provided an atmospheric end to the season.

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.
