Aaron Ramsey scored a hat-trick and Pierre-Emerick Aubameyang marked his debut with a goal as we delivered a slick, clinical performance to overwhelm Everton.
Our record signing’s first significant contribution was a slide-rule pass to his old friend Henrikh Mkhitaryan, who in turn laid on our opening goal for Ramsey.
Laurent Koscielny got the next one, putting his head in among the boots to nod past Jordan Pickford after Shkodran Mustafi flicked on Mesut Ozil’s corner.
Alex Iwobi laid on our third for Ramsey, a powerful shot from distance that Pickford could only tip into the roof of the net after a deflection off Eliaquim Mangala.
