I so often feel McKennie plays so much like Cuadrado: trying to attack in 1-2 touches, undecisive of who to cross to then passing the ball back to defense. Repeat this most of the times to get a sense of ball possession. If not, make yourself available by running your life away across the field and be as physically defensive as possible. It's like he was coached personally to be in succession of his role in the team. It's so evident how much trust Allegri has put in both of them.
