Olivier Giroud's incredible scorpion kick set Arsenal on the way to a victory over Crystal Palace which moved them up to third in the Premier League. With a cross from Alexis Sanchez delivered behind him, Frenchman Giroud elastically reached the ball with his left foot, looping it over his head and in off the underside of the bar. An Alex Iwobi header gave Arsenal a scrappy second before Palace briefly rallied to force saves from home goalkeeper Petr Cech. The win moves the Gunners back to within nine points of leaders Chelsea, while Palace stay 17th, two points above the relegation zone.
