It remained in the balance at half-time but the Gunners blew their London rivals away in the second-half. White made it two from close-range, with Chelsea strangely unaware to the danger of a short corner, before Havertz struck against his former club, finishing well under pressure after a sensational pass from Martin Odegaard. The German had his second midway through the second period, his low strike beating Petrovic off the inside of the post, and there was more misery to come for the visitors. Odegaard scooped a lovely ball over the top and White, seemingly attempting to square it across the face of goal, produced a perfect volley into the far corner.
