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.

Bayer 04 ended the year with a 3-1 win away at RB Leipzig and will go into 2026 in third place in the Bundesliga table, leapfrogging their opponents, who had previously not dropped a point at the Red Bull Arena this season.
