Verratti type pretty much. Plays the attacking mezzala in Cagliari's mid 3. He is the kind of player that you see dribbling around without losing the ball, with good vision, and always looking forward, not an AM though, goes hard on the tackle. Too hard as is common with kids (and Verratti himself).
Its always hard to say how good a kid will be. He is notable though, over most other kids in the league. He is a full starter in seria a at just 20 yo and is probably Cagliari's best player. Caldara, Spina, Orsolini, Gagliardini, Cristante, etc can't say the same as they either broke through older or haven't yet. Mandragora can say the same, another one of the highest rated kids in Italy. Him and Barella were starters together for the U20s and below at every level.
We'll know what happens to him soon enough but I think Juve has too many midfielders already.
