We have shown our presence on trips abroad, launched several initiatives and built partnerships,” says Fernando Carro, CEO of Bayer 04 Leverkusen. “In order to give Bayer 04 Leverkusen and the Bundesliga a permanently greater weight in global competition, we must continue to invest in this area in the coming years. We hope that Mr. Giammarioli, his commitment and his expertise will make an important contribution to the implementation of this project.”
“As part of our parent company Bayer, many areas of our club work with an international perspective every day,” says Holger Tromp, Director of Communications, Bayer 04, who heads Bayer 04’s international department. “Leonardo’s background in business development, his experience with sports and corporate structures, combined with his cross-cultural relationships, will be a great asset to our team.”
The filling of the most-recently vacant position comes almost a year after two extremely successful North American friendlies in 2022, including the Bayer 04 Mexico Tour 2022, in which the men's and women's teams traveled to Mexico. The highlight was a sold-out friendly against Toluca FC. Die Werkself also traveled to St. Louis, USA, last November for the inauguration of CITYPARK, the home stadium of the newly-crowned MLS Western Conference champions St. Louis CITY SC. Bayer 04 has also received various awards for its international social media channels and content offerings in other languages.

The Werkself continue their 2026/27 pre-season preparations with their third friendly against Belgian top-flight side KRC Genk at the Ulrich-Haberland-Stadion on Wednesday 29 July (kick-off 15:00 CEST). Werkself-TV is broadcasting the match live and in full in a stream from 14:50 CEST...

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.
