As a keeper, Angerer will almost certainly be forced to wear long sleeves during the World Cup, but her knees, thighs, and any exposed arm skin will also certainly get torn to shreds as she dives. Turf lets the ball speed and spin along the ground better. Expect lots of low shots and diving.
Not to mention players protesting the turf will contribute to other injuries, including catastrophic ACL and joint tears. It can also make players mentally hesitant to slide and tackle, both because they’re aware of seriously hurting themselves [and blood on the pitch is reason to take a player off for uniform change] and because they know they’re far more likely to cause permanent damage to the other player [who, by nature of the World Cup, is likely their friend and teammate].
All this in the absolute premiere soccer event in the world. But only for the women.
