FIFA will allow referees use new magic vanishing spray during next month's Club World Cup.
Gaining a few yards at a free-kick maybe a day of the past with the help of this magic spray. Refs will be assisted by the this aid that can line out a mark from where the wall should stand and then vanishes a minute later leaving no mark.
