Not much, but we're talking about a world class player. The other two aren't on that level.
Pogba has been nowhere near world class for the past few years. Let's drop this 'world class' nonsense already.
The only thing he has going for him is reputation from the past but that is quickly waning just like Dybala.
Wouldn't make sense to let go off Dybala for his injury record and unprofessionalism and then proceed to sign Pogba..
I'd stay away from him as far as I can.
Chiellini is retiring, Bonucci is on his last legs. Imagine a scenario where this guy becomes the locker room leader

Our transition to the new Union will be confirmed.
