I was thinking something similar to the guy below.
It would take a brave manager (and it might backfire) but the crux of the problem is that boxes (esp. 6 yard box) are increasingly becoming jam full of bodies (defenders as well as attackers) - resulting in it being increasingly hard for keepers to come for the ball & get it cleanly.
If a side cherry-picked 3-4 guys (with pace & final third nous) and placed them strategically - one each side wide on the half-way line. Another on the centre-spot and a 4th goal-side sitting right next to Rice.
What would risk-averse guys like Arteta do?
He'd sh1t himself. At the very least he'd mark them man-for-man. Probably with an extra body floating central too.
Suddenly you have ~8 fewer bodies in the box when a corner swings in. If you've got a mobile & commanding keeper along with your 5-6 best guys aerially maybe that swings the balance back to the defending side a bit?
It'd likely work very well initially but then get a bit cat & mouse, once the set-piece coaches have time to figure out counter-strategies.
