Securing 10 yards

How do you ensure that the attacking team gets 10 yards upon a free kick? Sometimes it takes a lot of work to move the wall that does not want to move back. The wall says they're too far from the ball. The attackers say the wall is too close.

But the basics are the same. If you determine that the wall is too close and that you need to get involved, make sure that everyone knows that the game would not resume without your whistle. Tell the attackers it is on your whistle. Tell the GK it is on your whistle. After that, tell the wall exactly where you want them to be.
