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.”

After a goalless and at times evenly-matched first half, Bayer 04's U19s ultimately suffered a heavy defeat at Manchester City. Coach Kevin Brok's depleted side - including five players who were part of the senior squad for the Champions League game in the evening - lost 6-0 on Matchday 5 of the UEFA Youth League.

A key player in that regard could be Aleix Garcia, the former City midfielder who ranks highly in several passing metrics in the Champions League this season. Here’s all you need to know ahead of the game in our matchday news.
