Mitroglu has less than a 1 in 2 goal ratio in a worse league than greece. It's not peanuts.
41 goals in 86 league games for by far the best team in greece. It's not a great record by any means. Most of his goals in europe have come against montpellier, liege, sheriff and a defence that included jenkinson, meade and squillaci.
Mirallas had 34 in 52 for the same team in the league btw
