This young goalkeeper seems to employ the unusual tactic of standing next to the goal instead of in front of it. Perhaps this was intended to lure the opposing team into a false sense of hope. Maybe she was a bit overconfident in her ability to execute acrobatic diving saves. Whatever the case may be, when the team in white makes a break for her goal, she springs into action and- smacks her face right into the post while they score on her empty net.
At the end of the clip, someone off camera is heard saying, "Is she down already?" in a way that makes it sound like this happens quite often, but not usually this early in the match.
