If he was a young player that made 2M a year, I'd be praising him on his qualities - ball carrying, protection, composure.
But since he came from Barcelona and makes 6/8M a year, I have to focus on what he cannot do. He's simply soft. Almost a liability on defense. Very poor instincts/reflexes. Tentative with the ball. You don't learn toughness..
All in all, he is a decent to good squad player. But definitely not a perennial starter on a team like Juventus.
This makes him immensely overpaid. Paratici should look for opportunities in the next mercato, while the guy is still young and some teams may think he's all potential. He's a 30-35M player. Sell him, sign one at this price range but with appropriate salaries/potential.
