A successful start for the 'Bayer 04 surgery': Virtual meetings have become commonplace since the start of the coronavirus pandemic. In these times where face-to-face meetings with more than one person in a room are to be avoided, this is a helpful alternative – which the Bayer 04 fan liaison section also sees as important. Fernando Carro, Bayer 04 CEO, and Meinolf Sprink (director of fans/community) recently held a remote discussion with Werkself fans on current issues relating to Bayer 04. In the coming months there will be other surgeries with Werkself supporters, different hosts and different subjects.
For the thirteenth time, the Leverkusen community foundation have carried out their 'Sterntaler' event. The aim is to provide joy to children and aged persons in the city.

"It's a matter close to our hearts every year and it goes without saying that we are happy to participate in the 'Sterntaler' event to show our commitment to the local community," said Meinolf Sprink, director of fans/community at Bayer 04.
