Sarri litterally and bluntly said his opinion isnt a factor in this saga. Said he likes Dybala and would buy him if he was in the market and not his coach already.
My point is that I doubt Sarri said he is a crucial player for this team and a definate starter. Maybe he did but I highly doubt that. Does he want him pushed out? No why would a coach not want him in the squad. Does Paratici think we need a 70 mil backup player that is on high wages? Probably not.
So you are right
1. Sarii doesnt make the call
2. Sarri rates him highly
3. Sarri wouldnt start him if he stayed.
4. Paratici doesnt think Dybala as a bench player is neccesary
Which of these are people disagreeing on? Sarri not having the final say does not mean he has no say in the matter. Italy operates that way at most clubs. Allegri has said multiple times there are scheduled meetings to discuss player personel and what he wants and needs and who currently is important. The board acts on that in the way THEY find appropriate
