It was a snapshot of the finishing ability that makes Pierre-Emerick Aubameyang a world-class performer and, for Arsenal and Mikel Arteta, the upshot was glorious.
Héctor Bellerín had driven the move and, when Nicolas Pépé worked a pass left to Aubameyang, the Arsenal captain knew in a heartbeat what he had to do. Using his right foot, he took the ball around Kurt Zouma as though the Chelsea defender was not there and then, with his left, almost in the same fluid movement, he produced a trademark dinked shot over the advancing Willy Caballero.
