Can't find an answer anywhere else but I'm sure someone her will know. I refereed an under 11 game yesterday, a player took a free kick just outside his own penalty area and knocks it sideways to his mate who isn't paying attention and has run forward. The striker moves to the ball but the defender who has taken the free kick shields the ball, stopping the attacker getting it until the keeper comes out and clears it. What's the rule there?
