That's the thing, he usually doesn't hug the wing, which is why we don't have any attacking threats coming from the left. In reality, it's not even a 4-3-3 because we tend to not have anyone wide left, unless Del Piero heads out to the touch line or the left-back wobbles his way down there, once in a blue moon. It really is a straight 4-4-2 with Marchisio playing more inside.
As I said before, this would work better with someone like Zambro at the back, but we don't have that. And without a left flank presence, we make it predictable to defend against Krasic.
