The Zenit coach has backed his former pupil to become a key figure at Allianz Arena, backing him to emulate his counterparts in status in Bavaria
Mircea Lucescu believes Douglas Costa has the potential to reach the levels of Arjen Robben and Franck Ribery and is the future of Bayern Munich.
Costa joined Bayern from Shakhtar Donetsk in 2015 and quickly became an important first-team player at the Allianz Arena.
