No there aren't. There's about 5 better than him atm max
If you believe this, then you are one of those who think he is special. Unfortunately, I'm not.
I think he looks good because he plays in a league, Italy, that is most favorable to defenders. On a team in that league that has the most experienced defenders, Juventuss, and he is the most technical of that crew.
In terms of individual capabilities there are no outstanding qualities outside his vision and long passing. He is not a great tackler, or interceptor of the ball, not a great header of the ball, not very strong physically ( I've seen him get muscled too many times), Not particularly vocal (so I don't know where the leader attribution comes from)
On the positive side, he has a decent slide tackle and takes good angles to the ball, has decent speed (I.e. faster than Otamendi). Show a a good knack on cornerkicks. And his try crowning jewel is his long balls, chips and lobs. He has a repertoire than a CM would envy.
But going to a new league with greater intensity, less support from the experienced core currently around him, matching up against more physical strikers etal, I seriously doubt he'd be the player he is at Juve.
That's just my view, I could be wrong. There are many young players I'll prefer including Sule, Tah, Chiriches, Marqhuinos, Laporte eyc. They might not be outright better players, but I prefer what they bring overall to what I think he will bring.
