Between 2014 and 2016 Maas, who played for Arminia Bielefeld and Hertha Berlin in the Bundesliga plus MSV Duisburg in the second division, was assistant coach to the current Bayer 04 head coach Peter Bosz. They were in charge at Dutch club Vitesse Arnhem for a total of 62 games in the Eredivisie. “In Rob Maas, we’ve appointed an innovative and strong-minded assistant coach who fits in really well here. He knows the Bundesliga and has already worked successfully with Peter Bosz. Rob will provide new ideas,” declared sporting director Simon Rolfes.
For Rob Maas, Bayer 04 are “a highly ambitious and very attractive club. That’s not just the perception in Germany but Leverkusen also have an outstanding reputation across Europe,” said Maas. “To be able to work with fellow coaches in developing an extremely exciting team is a fantastic challenge I’m really looking forward to.”

Since 2023, Bayer 04 has been organising regular free goalkeeping coach training sessions at the BayArena. As in previous years, the event attracted enormous interest in mid-October 2026. Around 140 participants – mostly goalkeeping coaches from the region, but also team and academy coaches as well as association staff – came to the Werkself stadium to gain expert knowledge on the subject of zonal marking. Through a theoretical keynote presentation and a practical session on the pitch, the participants gained insights into goalkeeping and goalkeeper training at Bayer 04.
