Napoli midfielder Eljif Elmas hit out at the refereeing after defeat to AC Milan.
Milan won the first-leg of the Champions League quarterfinal 1-0 last night, with Napoli upset with several decisions.
Elmas said, "I don't know what to say about refereeing, it's an incredible thing.
"He booked all our players, they committed the same fouls as us but no yellow cards.
"Something never seen before, also for this reason we were nervous at a certain point on the pitch."
