Arsenal looked a cut above Chelsea as they ran riot in Orlando against their London rivals.
The Gunners - for whom Oleksandr Zinchenko was making a debut - looked fitter, stronger and faster than Thomas Tuchel's side, with Gabriel Jesus pouncing on a defensive error to open the scoring with a fine chip over Edouard Mendy.
Martin Odegaard doubled the lead with a controlled finish in the first half, and although Chelsea were distinctly second best, Mason Mount struck the post with a fierce effort just before half-time after being found by Raheem Sterling.
