What sideline rules must the club enforce on match days?

The FAW's Positive Match Day Culture rules for 2026/27 say clubs and leagues must introduce these:

• No smoking, vaping or alcohol on the sideline. This includes 0.0% or zero-alcohol drinks that look like alcohol.
• Supportive sidelines. Spectators applaud and praise both teams, but don't shout, call out negatively or coach.
• Coaches can support players by asking questions that make them think for themselves, but must not continually shout instructions.
• "Behind the Line, Behind the Team":
  • Mark a buffer zone along both touchlines, ideally 2 metres wide (narrower if there isn't room), using barriers, cones or a painted line.
  • Only players, designated coaches and the first aider may be inside it.
  • All other spectators watch from behind the buffer zone.
  • No spectators on the goal line or behind the goals.
