When there's a free kick, you know how the referee always has to push the wall back again and again to get that ten yards away?
Well, now they have a spray paint can handy to spray a line right in front of the wall so they don't keep sneaking up closer to the ball on a free kick. Smart, don't know why FIFA didn't do this a long time ago. The referees have been doing it in the MLS for a few years now. Must be a bit of a pain though, for the refs, to run around the soccer field with the can of spray paint in their pocket.
And sometimes the referee gets the soccer shoes too! Here Referee Solis sprays the shoes of Mexican national team members Andres Guardado and Jose Vazquez when drawing the ine for the wall line for Portugal free kick.
