This video comes from yesterday's UEFA Champions League match between Chelsea and Valencia. Specifically, it's in the 87th minute after Valencia's Roberto Soldado scored on a penalty kick after Chelsea's Salomon Kalou went "up with his arm to dink it away from a Valencia head. What idiocy. What needless idiocy."
Those are Valencia fans celebrating the score being leveled at 1-1. One of them doesn't seem to like the camera or the viewing audience.
