They do it every world cup, they do it for outrageous goals they can show again and again and go 'wow, look how amazing this is, what a spectacle blah blah blah'.
Anyone can smash a ball goal-wards for it to move in the air and end up a stunning looking goal. Its pathetic.
Just use a ball that flies straight and true, then you see more of a spectacle. It really boils my piss.
