He's just not mature enough to lead and like most immature young talents he needs the right conditions and mentors to bring out his best. I feel he's been given the no. 10 and told, "you need to step up now", meaning that he now has to lead as he was once led by stars with years more experience than him and an inspiring motivator in Conte. He's too young to be a leader and now he has no one to lead him and this is what's caused this major form dip. You don't go from being that good to being this bad by fluke. It's purely psychological. The best thing for him would be a manager with strong character ala Conte. Allegri's relaxed style is hands off and that worked when he had an experienced squad but now these young players need a mentor who they revere, look up to and ultimately play for.
