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.

In their third friendly of this pre-season, Bayer 04 played on home soil for the first time – and won there too! The Werkself claimed a comfortable 4-0 victory against Belgian top-flight side KRC Genk at the Ulrich-Haberland-Stadion. Jeanuel Belocian (9’) and Nathan Tella (42’) gave a dominant Leverkusen a 2-0 lead at the break, which Afonso Moreira (51’) and Christian Kofane (53’) doubled after the break. Among the many second-half substitutions was Patrik Schick, who made his first friendly appearance of the summer.

After the children from the Bayer 04 Football Academy grilled Janis Blaswich and Simeon Rapsch last week, another group of 20 young Werkself fans gathered at the BayArena press conference room on Tuesday afternoon, 28 July . This time, the kids directed their questions at Tim Oermann and Jonah Berghoff. Defender Oermann raved about his school days, whilst talented midfielder Berghoff revealed to the young footballers, amongst other things, who his favourite player is – and he is also at Bayer 04. To round things off, the pair naturally obliged with all requests for autographs and selfies.
