Wow, not my perception of Pedri at all. It's the most important quality he lacks. I've made a point of watching him in isolation for a few games and he almost *never* scans when he doesn't have the ball. He's always running laterally to the ball, demanding it, and ball watching. He only scans just before receiving the ball but only to make sure no one is closing him down. He doesn't know where any of his teammates are if they are behind his filed of vision.
Once he has the ball, it's a different story. But it always takes him a beat to orient himself once he's received it. Wish he were in the same class as the players you mention, but he's nowhere close yet.
What I have noticed, however, is the FdJ has vastly improved in this regard. I've also made a point of watching him in isolation. Since being reintegrated into Flick's team, he's always scanning when he doesn't have the ball and playing with his head up. Used to be a much more self-absorbed player that slowed the offense down. I didn't rate him then. Kudos to him for this great improvement.
