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.

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.”
