Could be intentions. Zlatan always talks about not tracking back on defense to save his energy for surges in the box. I think it's the same for him, though we've seen him better in open spaces in previous years.
I don't think that their defense has been any thing amazing, we don't see them perform defensively often and they are neutralizing an uninspiring Belgian side that is toothless. We'll see what they can do against Holland or even Costa Rica :xfinger:
