Thats probably the hardest question you could ask. It’s difficult to answer because we always see those guys playing against players of their age group, or low tier teams as now in Serie C. Talking about this while being in B would be a lot easier.
Fagioli was for me without a doubt the most talented player last year. He’s injured now btw. His passing technique and vision were amazing last year. Dragusin as you said seems physically ready for a higher level. I have a soft spot for Ranocchia because he showed a lot of intelligent things, but that’s based on Primavera level and 2 games in Serie C.
There are other players I like as Vrioni, but he’ll be 22 this month, so it’s a giant step to the Serie A. I take their age in consideration when discussing this. The same for Rafia btw. If I had to choose I’d give all of them some minutes in Serie A games that are already finished tbh, I don’t see the point of not trying it. But preferably I choose players that stand out at this level, while being one of the youngest in the team.
But as said, it’s very difficult to say. And you?
