I watched the whole thing last night. Started off a bit cringe. But the game was really interesting.
Sadly, these lads have had about as much training as you or I when we start refereeing.
If anything these lads are in a better position than most others as they are experienced footballers, and have been given 1 to 3 coaching, and ongoing coaching throughout the game.
You could straight up use this video as evidence of how not to referee (which makes sense as these guys aren't referees).
Just points I noticed:
Ref says early, words to the affect of "I'm not doing cards in a charity match". Both team proceed to foul at every opportunity, basically just kicking people to the ground at certain points.
Kicking the ball away. At a point both teams just start taking the p***.
Getting too invested in arguments with players, at one point he says 'swear at me again and I'll kick your head in'. Just not really recommended, probably saved by it being a charity match, and one team being refs.
It is amazing the levels of abuse the refs are getting and based on
@es1 comment, I bet most don't even realise they're doing it. Death by a thousand cuts kind of thing.
