Watch him more closely then. Under pressure or not, Parker is almost always available for a short pass in the midfield.
But as I said before, when not under pressure that is not necessarily a good thing, and it's certainly not a difficult thing. If the other team is just sitting back, virtually anyone can move to within 5 yards of a teammate and then play a simple, cautious pass to a nearby player. I wouldn't call that superb movement. If his distribution was more positive, like Luka's, then it might be useful. But it's not. That's why IMO we need Luka (or even Livermore) to play deeper alongside Parker, and then VDV / Niko to play centrally ahead of them.
