Coach Tayfun Korkut will therefore need to find an alternative to a shooting star who has made 21 appearances in an outstanding breakthrough campaign in which he has successfully continued his studies off the field while passing every exam on it.

With Javier 'Chicharito' Hernandez making his comeback from injury on Matchday 30, Korkut is nevertheless not short of replacements up front, even if Havertz would have been an asset in a key fixture, with Leverkusen slipping to within four points of the bottom three following defeat to Freiburg last weekend.
