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.”

This afternoon, Saturday 24 January (kick-off: 15.30 CET), Bayer 04 host SV Werder Bremen, who are winless in their last seven league games. Nevertheless, in their last outing, a 3-3 draw against Eintracht Frankfurt, where they conceded a late equaliser, the Green and Whites did show their team spirit. The Werkself, led by birthday boy Patrik Schick, will be looking to counter this and secure their first three points of the new year on this ‘!Never Again’ remembrance matchday to commemorate the victims of National Socialism. Read on for the latest information in today's matchday news.
