We dont know? Well thats an improvement, because it sounds like you guys are talking like we know Ariaudo is proven quality but is being short changed by the club. Yes, the management and the club would know (but you are still questionning them like you know better), and there is a reason why he doesnt play (we are a club in a real competetive level, take that in consideration), so its better to get playing time elsewhere and prove himself as a valiable candidate to rejuvenate our defence with in next season or the one after.
And yes, Kjaer and Rannocchia are better then him (more likely to get to start then him in that case). I have seen Rannocchia hyped too soon, but seen him enough in Azzurrini to know he is better, and seen him in his Serie A debute dominating two world class strikers. Same with last time I saw Kjaer in a full game being cancelling Zlatan out well. Kjaer's inconsistency and errors arent pointed out enough for my liking, but he is someone who has real good qualities and worth buying nontheless.
