In conversation with host Cedric Pick, the currently in-demand specialist for internal medicine talked about the latest developments with the coronavirus pandemic, the latest political decisions at state level plus his wide range of duties at the Werkself. The 57-year-old medic also provided insights into the club’s hygiene protocol, the different testing procedures as well as the handling and chain of action with positive test results as was the case recently with Werkself defender Edmond Tapsoba after his return from international duty.
The Leverkusen-born doctor, who, in addition to his role at Bayer 04, is the director of a group practice in Leverkusen-Quettingen, outs himself in the entertaining dialogue as a longstanding Bayer 04 fan, a supporter of the Werkself from the stands long before he became the club doctor. In his very first season of his employment at the club, which ‘Kalla’ describes as a coincidence, he was able to follow the historic 2002 season first hand with the three runners-up finishes – so defining and indescribable as many short-notice and short overseas trips involved with transfers.
In the entertaining discussion, Karl-Heinrich Dittmar talks about his values, his multifaceted workload, lack of time and his pride in the club’s training and rehab centre the Werkstatt. The father of four not only revealed a great sense of humour but also loads of empathy.
In addition to the opening jingle, the Werks11 podcast also includes other items (including ‘My top 04’, ‘Either...or...’). Other guests speaking are his former boss Reiner Calmund plus former Bayer 04 keeper René Adler who surprise Karl-Heinrich Dittmar with a question.
Moreover: From now, the Werks11 podcast will be available every two weeks. The next episode will be available on Tuesday 15 December.

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.
