Very obvious it’s not perfect, has it even been a success? That’s up for debate; I think the parameters need tweaking at least but there’s potential.
As so many vehemently disagree about the penalty it’s clear and obvious that it’s not clear and obvious so shouldn’t have been given - but I still say I think it’s a handball, just the awkward way he swings a let and moves his arm towards it, he’s misjudged it and got it all wrong.
Its clear though that I may need to study up on the rules!
