Indeed - doesn't need to even be a particularly high level.I was referring to grounds (such as football league grounds) which have stands on all four sides, not pitches with RESPECT barriers.
I refereed an U15 game in a Respect league on this pitch a few weeks ago. As you can see, not only is there a barrier behind the goal, there is a stand!
Should I let spectators stand behind the barrier behind the goal? Should I let them sit in the stand? Should I let them sit in another stand behind the dugouts and therefore on the same side as the coaches?
