A sideline attack at a men's state league soccer game in Perth has prompted pushback after a glass bottle was thrown at a player.
The scuffle caused mayhem in the stands just weeks after spectators were banned following a similar brawl at another club.
The beer bottle was pelted at Mandurah FC players as they walked from the field.

9News understands there has been an ongoing feud between players and spectators.
