The beauty of what Marchisio is doing, is not only the fact that he has been sublime in his role as a CDM, being the link between the defense and the midfield, with the way he anticipates, cuts off angles, and basically allows the defense to push further up the pitch than at any point I can remember in the last several years (Seriously, when was the last time any of us had seen Chiellini take the ball from behind the mid-stripe to the opponents box like we did a couple of weeks ago)
It's that despite playing farther back and having the role of covering for Pogba and Vidal when they push further up, he is still dangerous as fuck outside the box when he gets in position to play the ball and shoot.
