Pjanic and Costa are the only ones on the pitch right now moving the ball and trying to build attacks. But every time they pass the ball to Khedira, Stu, Higgy, Asa, etc, the game is slowed back down, and any build-up is negated.
Chievo are sitting so deep, that there is no space for any of our attackers once we get near the box. We need De Sciglio to overlap to pull defenders away.
