Following up a lead from uber trolley hunter Am Bioran, I duly found the one he'd pointed out; snapped it and carried onwards to stand beside Dylan Easton at to Alex's game. Until it erupted into violence. 

One of Alex's team mates got involved in a messy confrontation. The team mate called the opposition player a *** ****. The opposition player turned round and hacked him, both legs, ball isn't even in play. The victim's dad rushed on to see his son was ok; the aggressors dad lamped him, saying ' how dare your son call my boy a *** ****' and... yes. Well. Match abandoned. 
Someone asked if we get awarded the game.

Only if it's a knockout competition, I mused.
