PSG were awarded a free kick against Chelsea just before half time. The ref duly marked the spot with a wobbly semi circle of vanishing spray.
David Luiz picked up the spray and moved it to another spot.
Zlatan took the free kick from the new spot and missed anyway.
The ref probably did not book Luiz because its a brand new foul which hasn’t been entered in the rule book yet.
Maybe refs will have to start marking the spot with an X to prevent players from moving the vanishing spray before it vanishes.
Moving an X is much harder than moving a wobbly semi circle.
