dybala's shooting is world class, no doubt about that. he's also very intelligent, has great vision on the field, he can use spaces very effectively. what he lacks is pace, psychical strength to be more consistent and physical presence. he's our most talented player by far, but not the most important one. i wouldn't sell him, i'm convinced he's got the pirlo, vidal, pogba, tevez level of potential class and he would be very hard to replace, but i'd be surprised if he wanted to stay and marotta wouldn't want to cash in on him.
