Actually in my opinion, it was the fault of the ref. Not the goal itself, but before that there was an offside (It's called an offside right?), but the ref didn't whistle so the game continued. If he did, it might had been a different game, maybe a different winner. Also, it seemed like it wasn't about who could make the most goals, but about how many cards the ref could give. neutral
I hope no one feels offended by this, but it's my opinion.
