When you see who are the trequartisti in this league, you wont be too quick too judge. Milan have Honda, Napoli Insigne (Hamsik RCM this season), Inter...who, Perisic/Ljajic? Roma psuedo Pjanic (more of a 3 man midfield, but he is the best one when he isnt inconsistent half the season), Lazio dont play with one. So essentially there isnt much of a competition for this role.
