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.”

Once the final whistle was blown, it was time to take a deep breath. 2-0 down and a 5–2 win in the end.

Or, to put it another way: Edmond Tapsoba’s first Bayer 04 brace, a clinical penalty from Patrik Schick, yet another precision strike from Hofmann and a blistering volley from Lucas Vázquez. Each goal more beautiful than the last! After the match, head coach Carles Martínez praised his team’s commitment above all else and the fact that they never lost belief in themselves. The Werkself review.
