Had a game on Sunday on a very well looked after pitch. checked nets looked at lines nice fresh marked white lines. Started game and in the 80th minute i gave a free kick which was on the center of the penalty arc. so in my head did not need to walk it out its 10 yards, the player who was over the ball said that is not ten yards ref. the wall was on the penalty spot. I told him it was 10 yards but i walked it out and it was 7 yards. such a good pitch i did not think the measurements could be wrong, I took the wall back three more yards, But i started thinking if there is a pen were will all the player stand three yards behind the box line.
