there's no way you can look at that play and say the Japanese defender had her arms in an unnatural position or was intending to block it. She was clearly moving her arm out of the way, but from 3ft away she had no chance. And it's not even like the ball hit her arm straightaway, it bounced off her rib area.
VAR is fucking lame and the people who say it makes the game better can fuck right off. I know I'm in the minority in this and I accept more replays are in our future, but it makes things excruciating IMO.
